In drivers/gpio/gpio-samsung.c, there are certain structures
and functions which are not getting used if the particular
CPU is not selected. These code segments are moved under CPU
specific macros to remove compilation warnings.

It has been build tested with s3c2410_defconfig, s3c6400_defconfig,
s5p64x0_defconfig, s5pc100_defconfig, s5pv210_defconfig and
exynos4_defconfig.
The patch has been rebased onto
