serial: amba-pl011: honour delay_rts_before_send for every write
While the driver waits out delay_rts_before_send, another write calls
pl011_start_tx() again. pl011_rs485_tx_start() then switches straight
to SEND, and the data goes out before the delay has passed.
Leave the start to the trigger_start_tx timer while it is pending.
