ARM: SAMSUNG: Let s3c_pm_do_restore_*() take const sleep_save

The restore functions do not modify the passed in struct sleep_save,
so that parameter can be const.

This allows us to pass in const struct.  This allows us to use const
structs sleep_save to define system registers that will always be
restored to a constant value.
