arm64: dts: phygate-tauri-l: add overlays for RS232 and RS485
UART2 and UART4 can used in following combination,
2 x RS232:
- UART2 and UART4 without flow control
- MUX selection GPIO3_20 must be held low
1 x RS232 + 1 x RS485:
- UART2 - RS232
- UART4 - RS485
- MUX selection GPIO3_20 must be held high
- RE/DE for RS485 controlled with GPIO3_25
1 x RS232 with flow control:
- UART2 - RS232
- MUX selection GPIO3_20 must be held low
