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.
