[PATCH v4 RESEND 4/9] serial: sc16is7xx: remove redundant check in rs485_config

[Lino Sanfilippo]

In uart_set_rs485_config() the serial core already ensures that only one of
both options RTS on send or RTS after send is set.

So remove this check from the drivers rs485_config() function to avoid
redundancy.
