Stephen Boyd 7bce696b07 gpio: Make gpio-msm-v1 into a platform driver
Doing this removes the dependence of this driver on the
msm_iomap.h and cpu.h mach include headers provied by MSM. This
is necessary to support single zImage work in the future and
allows us to remove cpu.h entirely and brings us closer to
removing msm_iomap.h.
