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. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Denis Turischev <denis@compulab.co.il>
