gpio/it8761e: Restrict it8761e gpio driver to x86.

This driver does an unconditional read of io space during module init which
causes a bad dereference on ARM.  It looks to me like this is an x86 only
drivers, so restrict it to only compile on x86.

          Say yes here to support GPIO functionality of IT8761E super I/O chip.
