i want to move sirfsoc_of_pwrc_init and sirfsoc_of_pwrc_init to
sirfsoc_pm_init as only suspend entries need them. then the result is
like:

 int __init sirfsoc_pm_init(void)
 {
+       sirfsoc_of_pwrc_init();
+       sirfsoc_memc_init();
        suspend_set_ops(&sirfsoc_pm_ops);
        return 0;
 }
