ARM: shmobile: add common extra gpio functions Current gpio frame work doesn't have the method to control just pull up/down/free, but some SH-ARM boards need such kind of operation. This patch adds common extra gpio functions for SH-ARM. But these functions should be replaced by correct gpio function in the future.

ARM: shmobile: use __iomem pointers for MMIO ARM is moving to stricter checks on readl/write functions, so we need to use the correct types everywhere. This patch is a bit ugly for shmobile, which is the only platform that just uses integer literals all over the place, but I can't see a better way to do this.
