Add support for the Anbernic RG-ARC S and RG-ARC D devices. These
devices feature the following:
- Rockchip RK3566 SoC
- 4 inch 480x640 display (rotated)
- Goodix multi-touch (ARC D only, untested as I lack the device)
- 1GB (ARC S) or 2GB (ARC D) of RAM
- 2 SDMMC slots
- eMMC (ARC D only)
- Realtek 8821CS WiFi/Bluetooth
- External stereo speakers
- 6 face buttons (A, B, C, X, Y, Z) along with a D-Pad and start and
select buttons.
- A PWM vibrator.
Note that the Goodix touchscreen on I2C2 is not defined, as I lack
the necessary hardware to confirm it works correctly with the mainline
driver.
