ARM: dts: sunxi: add support for Anbernic RG-Nano

Browse source

The Anbernic RG-Nano is a small portable game device based on the
Allwinner V3s SoC. It has GPIO buttons on the face and side for
input, a single mono speaker, a 240x240 SPI controlled display, a USB-C
OTG port, an SD card slot for booting, and 64MB of RAM included in the
SoC. There does not appear to be a crystal feeding the internal RTC so
it does not keep proper time (for me it ran 8 hours slow in a 24 hour
period). External RTC works just fine.

Working/Tested:
- SDMMC
- UART (for debugging)
- Buttons
- Charging/battery/PMIC
- Speaker
- RTC (external RTC)
- USB
- Display
