serial: 8250: handle __start_tx() call in start_tx()
As either start_tx_rs485() or start_tx() calls __start_tx() as the last
line of their logic, it makes sense to just move that call into
start_tx(). When start_tx_rs485() wants to defer tx using timer, return
false so start_tx() can return based on it.
Reorganize em485 code in serial8250_start_tx() so that the return can be
shared for the cases where tx start is deferred.
