gpiolib: of: Only compile in MT2701 quirk when it is needed. 

The compiler cannot workout if this is actually needed or not
so machines that will never need this code also get it.

For example:
m68k-linux-gnu-nm vmlinux | grep mt27
00135742 t of_find_mt2701_gpio

Add some ugly ifdef'ery to get rid of it.
