Crescent Hsieh 55edf8511f serial: 8250_mxpcie: enable automatic RTS/CTS flow control
The MUEx50 UART supports automatic RTS/CTS flow control via the enhanced
feature register.

Implement a mxpcie-specific set_termios() callback that enables MUEx50
auto-RTS/auto-CTS when CRTSCTS is requested and disables it otherwise.
Keep the 8250 port status flags in sync with the hardware configuration.
