ARM: SAMSUNG: Add SAMSUNG_PM config option to select pm

This patch enables the selection of samsung pm related stuffs
when SAMSUNG_PM config is enabled and not just when generic PM
config is enabled. Power management for s3c64XX and s3c24XX
is enabled by default and for other platform depends on S5P_PM.
This patch also fixes the following compilation error's when compiling
a platform like exynos5440 which does not select pm stuffs.
