Several drivers that support setting the RS485 configuration via userspace implement one or more of the following tasks:
in case of an invalid RTS configuration (both RTS after send and RTS on send set or both unset) fall back to enable RTS on send and disable RTS after send
nullify the padding field of the returned serial_rs485 struct
copy the configuration into the uart port struct
limit RTS delays to 100 ms
Move these tasks into the serial core to make them generic and to provide a consistent behaviour among all drivers.
