Add Powkiddy RGB20SX

From: Chris Morgan <[email protected]>

Add support for the Powkiddy RGB20SX handheld gaming console. The device is mostly identical to the RGB30 but with a few key differences. Namely, the size of the battery and presense of a function button differ from the RGB30; these changes cannot be detected at runtime and necessitate a distinct devicetree.

The Powkiddy RGB20SX is a portable game console extremely similar to the existing RGB30 console. The key differences from the RGB30 are as follows:

- Realtek RTW8723DS WiFi and Bluetooth.
- UART pads for debug console (UART2).
- A function button (ADC channel 0).
- A much larger battery (5000 mAh).

Otherwise, the device is identical to the RGB30, including the hard-coded value on ADC channel 1 used to identify the device at runtime.
