ARM: SAMSUNG: Add s3c_gpio_cfgall_range() function
Add a function to configure a range of GPIOs function and pull in one go, mainly for the SDHCI and framebuffer helpers which tend to do this. Signed-off-by: Ben Dooks <ben-linux@fluff.org> [kgene.kim@samsung.com: Fix small comments] Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
