prep_pci: Simplify I/O endianness
The prep PowerPC CPU is Big Endian. An explicit byte swap therefore effectively becomes Little Endian. Remove explicit byte swaps and mark as Little Endian. Signed-off-by: Andreas Färber <andreas.faerber@web.de> Reviewed-by: Alexander Graf <agraf@suse.de> Cc: Michael S. Tsirkin <mst@redhat.com>
