we talk about 12bytes and here it's force to put a ifdef in the gpio drivers
in platform_device we don't do so. So why should be do it here??
Drop the ifdef will ensure evenif we compile the code without OF_GPIO that all
the work can compile
we recently introduce IS_ENABLED & co to drop the maximum of ifdef
here it's the same idea
