Subject: [PATCH 6/9] serial: max310: remove redundant code in rs485_config

When RS485 is configured by userspace the serial core already nullifies the
padding field of the returned configuration struct. Doing the same in the
drivers rs485_config function is redundant, so remove the concerning
code in this function.
