The ppc32 common config runs also on PReP/CHRP, which uses PC style IO

ppc can boot one single binary on prep, chrp and pmac boards.
ppc64 can boot one single binary on pseries and G5 boards.
pmac has no legacy io, probing for PC style legacy hardware leads to a
hard crash:

drivers/input/touchscreen/mk712.c pokes at 0x262 and other IO ports.
A comment in the driver suggests that it is only used on Gateway
computers. Should the driver be X86 only?
