Review and refactor DTS code for Youyeetoo R1 V3:

- Reworked FAN code for improved support; now correctly operates when the temperature reaches 55°C.
- Fixed CAN pinctrl interface; pin assignment aligned with the schematic.
- Added PHY supply reference to Ethernet configuration.
- Removed redundant code, including xgpio on pinctrl.
- Renamed `gpio-key` to `gpio` for clearer reference.
- Moved LCD backlight PWM controls to the appropriate function.
