Whether these lines exist depends on SoC and UART instance inside the SoC. Whether these lines can be used for hardware flow control depends on board wiring. Amend the DT bindings with an optional property to indicate that RTS/CTS hardware flow control lines exist, and can be used as such, according to the Generic Serial DT Bindings.
