Split WM1A/WM1Z because they don't have the same KAS. On newer devices, the KAS
is actually 64 bytes, not 60. The strange thing is that "get_dnk_nvp kas" returns
60 bytes whereas "get_dnk_prop kas" returns 64, not sure why.

It doesn't work properly and interferes with the power button in the keymap.
Rework WPS keymap a bit to make single-tap power emulate lock.

Unsure why this is happening, but now we detect and recover errors at
startup.
Also clean up the mismash of printf(), DEBUGF(), etc in favor of panicf() for the really serious stuff and logf() for everything else.

Note: PCM mix buffer sizes are _way_ too small for these high bitrates
(We really need to make the mixer stuff use dynamic buffer sizes based
on the bitrate. Maybe pre-allocate a max size based on upper bitrate limit,
but use only part of it at lower bitrates? So we can have sane latency..)

* xduoo x3ii/x20: Better line out support
* less granular volume settings (too many steps before)
* Better handling of swiching sample rates
* Log actual sample rate in debug menu

Additional integration [re]work by myself
Change-Id: I63af3740678cf2ed3170f61534e1029c81826bb6
* Kill LCD when turning off the backlight
* Fix logic errors in lcd_enable() calls
* Use ioctls instead of sysfs to twiddle lcd enable

Can be disabled at runtime by setting hold switch.
Boosts sysbench sequential write performance by 34-58%
Change-Id: I060c9d7dddc1b448f18aa46af8f8aff046e07843
* DMA Bulk IN (ie our TX) results in sequential transfers 33-68% faster.
* DMA Bulk OUT (ie RX) is mostly stripped out due to complete brokenness.
* Interrupt and control endpoints remain PIO-driven.
Other improvements:
1) Use consistent endpoint references (no magic numbers)
2) Greatly enhanced logging
3) DMA support can be compiled out completely
4) Setting lockswitch will disable all DMA operations at runtime
5) Much more robust error checking and recovery

Fixes deficiencies with the button system on the X3
The x3 has an interesting button layout.
Multiple key presses are NOT supported unless
[BUTTON_POWER] is one of the combined keys
As you can imagine this causes problems as the power button takes
precedence in the button system and initiates a shutdown if the
key is held too long
instead of BUTTON_POWER use BUTTON_PWRALT in combination with other keys
IF using as a prerequsite button then BUTTON_POWER should be used
Multiple buttons are emulated by button_read_device but there are a few
caveats to be aware of:
Button Order Matters!
different keys have different priorities, higher priority keys 'overide'
the lower priority keys
VOLUP[7] VOLDN[6] PREV[5] NEXT[4] PLAY[3] OPTION[2] HOME[1]
There will be no true release or repeat events, the user can let off the
button pressed initially and it will still continue to appear to be
pressed as long as the second key is held
Tree scrolling is PLAY+NEXT or PLAY+PREV

Group commands for a bit more speed
bitdelay was not being inlined
lower bitdelay to 12 cycles
Clean-up magic numbers

* Increase audio buffer size to better handle IRQ latency (256->2048)
* Ensure DMA engine is idle prior to starting transfers
* Set AIC to repeat last sample in case of underflows

Based on code originally written by Amaury Pouly (g#1789, g#1791, g#1527)
but rebased and heavily updated.
Change-Id: Ic794abb5e8d89feb4b88fc3abe854270fb28db70
only check button values with adc when buttons are actually pressed
battery level check frequency is now around 30 seconds
switched to polling for the battery voltage w/ timeout
Ifdef functions Allow BACK OPTION PLAY to be the first of a two key combo
