serial: general fixes in the serial_rs485 structure
Fix several issues related to the RS485 interface:
- It adds the flag SER_RS485_RTS_BEFORE_SEND that was missing from the
serial_rs485 structure (even if "delay_rts_before_send" was existing)
- It adds a further "delay_rts_after_send" field for those drivers that
can have a delay after send (e.g., atmel_serial)
- It fixes the usage of the structure in the atmel_serial driver (where
"delay_rts_before_send" should be used instead of "delay_rts_after_send").
