tty/serial: atmel: Add is_half_duplex helper
commit f3040983132bf3477acd45d2452a906e67c2fec9 upstream.
Use a helper function to check that a port needs to use half duplex
communication, replacing several occurrences of multi-line bit checking.
Fixes: b389f173aaa1 ("tty/serial: atmel: RS485 half duplex w/DMA: enable RX after TX is done")
