b25d8457bc Shanling Q1: fix DAC power mode switching
The OST prescaler bugfix (7a5130a277) broke runtime switching
between 1.0V and 2.0V modes. The 1ms delay after shutting down
the DAC isn't long enough to reset it, so it gets stuck in the
power mode assigned at boot. Change the delay back to 4ms, the
effective value prior to the OST bugfix.

dac3175445 audiohw: avoid magic numbers for DAC power mode
Define proper symbolic constants for power mode. Also allow
targets to define the default power mode setting.

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.
