[PATCH 1/5] nomadik: move gpio to plat-nomadik

Move the Nomadik GPIO driver to plat-nomadik so that it can also be used
on the Ux500 platform.
The mach-nomadik include/mach/gpio.h is replaced by one that includes
the one now in plat-nomadik, so that code doesn't need to include the
one in plat specifically, and can instead use <linux/gpio.h> as usual.
