With CONFIG_ARCH_MULTIPLATFORM, we can no longer have
our own mach/gpio.h included by the kernel-wide linux/gpio.h
header, and disabling the gpio-samsung driver means we cannot
use any of the private interfaces. This patch disables
all code referring to the driver and gets things to build
again, but surely breaks a lot of stuff in the process.
Thomas Abraham alrady has a proper set of patches to
address this.
Do not apply.
