Aidan MacDonald 4c60bc9e68 New port: Shanling Q1 native 
- Audio playback works
- Touchscreen and buttons work
- Bootloader works and is capable of dual boot
- Plugins are working
- Cabbiev2 theme has been ported
- Stable for general usage

Thanks to Marc Aarts for porting Cabbiev2 and plugin bitmaps.

There's a few minor known issues:

- Bootloader must be installed manually using 'usbboot' as there is
  no support in jztool yet.

- Keymaps may be lacking, need further testing and feedback.

- Some plugins may not be fully adapted to the screen size and could
  benefit from further tweaking.

- LCD shows abnormal effects under some circumstances: for example,
  after viewing a mostly black screen an afterimage appears briefly
  when going back to a brightly-lit screen. Sudden power-off without
  proper shutdown of the backlight causes a "dissolving" effect.

- CW2015 battery reporting driver is buggy, and disabled for now.
  Battery reporting is currently voltage-based using the AXP192.

/* Use AUDIOHW_SETTING to create an audio setting. There are two ways to use this
* macro:
* AUDIOHW_SETTING(name, unit, nr_decimals, step, min, max, default)
* AUDIOHW_SETTING(name, unit, nr_decimals, step, min, max, default, expr)
*
* It is important to understand that each setting has two scales: the hardware
* scale and the user scale. In the first form of the macro, they coincide.
* In the second form, the conversion from hardware to user is done by the
* expression [expr] provided in the extra argument (see examples below). The
* hardware scale ranges from [min] to [max], in steps of [step]. The default value
* is [default]. Furthermore, when displaying the value to the user, [nr_decimals]
* gives the number of decimal points to display. Thus if [nr_decimals] is 0 then
* a value of x means x [unit]. If [nr_decimals] is 1 then a value of x means
* x/10 [unit] and so on. Note that both [nr_decimals] and [unit] are irrelevant
* to the hardware, they simply provide a flexible way to show natural value to
* the user. When you want the user scale to be different than the hardware scale,
* you must provide [expr], an expression that can use the variable "val", which
* represents the hardware value, and converts it to the user value. The [expr]
* can involved a function call in very complicated/nonlinear cases, as long as
* the function does not have any side-effect. Finally, the [name] parameter
* must be one of the settings listed in audiohw_setting.h
*
* Examples:
*
* AUDIOHW_SETTING(VOLUME, "dB", 0, 1, -100, 12, -25)
* This describes the volume setting. The values are in dB (no decimal). The
* minimum value is -100 and the maximum is 12, with a step of 1 and a default
* value of -25. This means that the hardware can take any of the following value:
* -100, -99, -98, ..., 11,12
* Since there is are decimals and no conversion expression, a hardware value of
* x means x dB. So a value of -25 means -25 dB, a value of 5 means 5 dB.
* WARNING VOLUME is actually special: whatever scale you choose, the sound code
* will always set the volume by calling audiohw_set_volume() with a centibel
* value (ie it will not perform any conversion). Thus it is strongly advised
* that you always choose a VOLUME scale with precision 1 (centibels) and no
* hardware conversion.
*
* AUDIOHW_SETTING(MDB_CENTER, "Hz", 0, 10, 20, 300, 60)
* This describes the MDB (dynbamic bass) center. The values are in Hz (no
* decimal). The minimum value is 20 and the maximum is 300, in steps of 10
* and a default of 60. Thus hardware can take any of the following value:
* 20, 30, 40, ... 290, 300
* Since there are no decimals and no conversion expression, a hardware of x
* means x Hz. So a value of 60 means 60 Hz.
*
* AUDIOHW_SETTING(BASS, "dB", 1, 15, -60, 90, 0)
* This describes the bass control. Since there is one decimal, the values are
* in tenth of dB. The minimum value is -60 and the maximum is 90, in steps of
* 15 and a default value of 0. Thus hardware can take any of the following value:
* -60, -45, -30, ... 60, 75, 90
* Since there is one decimal, a hardware value of x means x/10 Hz. So a value
* of 60 means 60/10 = 6 dB. A value of -45 means -45/10 = -4.5 dB.
*
* AUDIOHW_SETTING(DEPTH_3D, "%", 0, 1, 0, 15, 0, (100 * val + 8) / 15)
* This describes 3D enhancement control. The values are in percentage (no
* decimal). This setting makes a difference between hardware and user scale.
* The minimal hardware value is 0 and the maximum is 15, in steps of 1 and
* a default of 0. Thus hardware can take any of the following value:
* 0, 1, 2, ... 14, 15
* Because of the conversion expression, a hardware value of x means
* (100 * val + 8) / 15) %. A hardware value of 0 means (100 * 0 + 8) / 15) = 0 %
* because the result must be an integer (8 / 15 = 0). A hardware value of 1
* means (100 * 1 + 8) / 15 = 7 %. A hardware value of 15 means
* (100 * 15 + 8) / 15 = 100 %. In fact, from the user point of view, the range
* of available values is:
* 0%, 7%, 13%, 20%, ..., 93%, 100%
*
* AUDIOHW_SETTING(LEFT_GAIN, "dB", 2, 15,-345, 1200, 0, val * 5)
* This describes the left gain. Since there are two decimals, the values are in
* hundredth of dB. This setting makes a difference between hardware and user scale.
* The minimal hardware value is -345 and the maximum is 1200, in steps of 15 and
* a default of 0. Thus hardware can take any of the following value:
* -345, -330, -315, ..., 1185, 1200
* Because of the conversion expression, a hardware value of x means
* val * 5 hundredth of dB or, in other words, (val * 5)/100 dB (where we keep two
* decimals). A hardware value of -345 means -345 * 5 = -1725 hundredth of dB
* = -17,25 dB. A value of -330 means -330*5 = -1650 hundredth of dB = -16,50 dB.
* A value of 1200 means 1200 * 5 = 6000 hundredth of dB = 60 dB. In fact,
* from the user point of view, the range of available values is:
* -17.25 dB, -16.60 dB, ..., 59.25 dB, 60dB.
*
* AUDIOHW_SETTING(DEPTH_3D, "dB", 0, 1, 0, 3, 0, depth3d_phys2_val(val))
* This describes 3D enhancement control. The values are in dB (no
* decimal). This setting makes a difference between hardware and user scale.
* The minimal hardware value is 0 and the maximum is 3, in steps of 1 and
* a default of 0. Thus hardware can take any of the following value:
* 0, 1, 2, 3
* Because of the conversion expression, a hardware value of x means
* depth3d_phys2_val(x) dB. If for example the conversion functions is:
* int depth3d_phys2_val(int val)
* {
* return val == 0 ? 0 : val * 5 + 30;
* }
* then from the user point of view, the range of available values is:
* 0 dB, 35 dB, 40 dB, 45 dB
