Add support for PIO mode for GCM mode.

why do you require PIO ? Is there any situation where DMA can't be
used? What would that case be ?

Cannot think of any case where DMA can't be used.
But the current driver already supports PIO for all other AES modes.
I do not want to break it, so added support for PIO  for GCM :)

Thanks and regards,
