tty/serial: at91: fix I/O accesses on RHR and THR for AVR32
This patch fixes I/O accesses on the Receiver Holding Register and on the
Transmitter Holding Register. Indeed AVR32 can only perform 32bit I/O
accesses on registers: using 8bit I/O accesses would read or write garbage
data.
Fixes: commit b5199d468177 ("tty/serial: at91: add support to FIFOs")
