ARM: SAMSUNG: Move pm-check.c to plat-samsung

Move the pm-check.c file to plat-samsung for all Samsung SoC users, and
update Kconfig names to make them SAMSUNG_ instead of S3C2410_

Sed expresions used to make the change:

    s/S3C2410_PM_DEBUG/SAMSUNG_PM_DEBUG/g
    s/S3C2410_PM_CHECK/SAMSUNG_PM_CHECK/g
