Add devicetree binding documentation for the FriendlyARM NanoPi R4S.
Changes in v2:
- Disable display for NanoPi R4S (reference commit: 74532de460ec)
- Light "sys" LED on NanoPi R4S (reference commit: 833821eeab91)
Changes in v3:
- Dropped non-existent node `display_subsystem`
Changes in v4:
- Correctly dropped `display-subsystem` node
- Dropped meaningless `pwm-fan` node
- Dropped wrong `sdmmc` node
- Disabled `i2c4` and `uart0` as they don't exist in the design
- Format fixes
