The PL022 interrupt registers have bits allocated as:
 0: ROR (receive overrun)
 1: RT (receive timeout)
 2: RX (receive FIFO half full or less)
 3: TX (transmit FIFO half full or less)

A cut and paste error meant we had the wrong value for
the PL022_INT_RT constant. This bug doesn't affect device
behaviour, because we don't implement the receive timeout
feature and so never set that interrupt bit.
