OMAP7XX: GPIO: Remove duplicate omap850 code
This patch is part of a series which unifies all duplicated code between omap730 and omap850. All cpu checks are converted to cpu_is_omap7xx() and CONFIG_ARCH_OMAP850 is added to all CONFIG_ARCH_OMAP730 checks. Signed-off-by: Alistair Buxton <a.j.buxton@gmail.com> Reviewed-by: Zebediah C. McClure <zmc@lurian.net>
