arm64: dts: rockchip: Add Asus Tinker Board 3 and 3S device tree
Add initial device tree support for Asus Tinker Board 3 [1] and 3S [2],
which are SBCs based on the Rockchip 3566 SoC.
The "3S" version ("S" for "storage") just adds a 16 GB eMMC
and a "mask ROM" DIP switch (to mask the eMMC and enter "Mask ROM"
mode for recovery) to the "3" version.
This adds support for:
- Debug UART (/dev/ttyS2)
- SD card (/dev/mmcblk1)
- eMMC (/dev/mmcblk0, only on Tinker Board 3S)
- I2C:
- i2c0 (internal bus with a PMIC and regulators)
- i2c2 (internal bus with an at24 eeprom and an RTC device)
- USB 2.0 ports
- 2 GPIO LEDS
