Xianglong Du 3916b09eed drivers/rtc/rtc-sirfsoc.c: fix kernel panic of backing from hibernation ...

RTC settings will be lost if power supply is cut off after hibernation
finished, but the current "restore" function does not restore RTC related
settings, this causes rtc_read_time failure and kernel panic:

  rtc rtc0: **** DPM device timeout ****

this patch uses SIMPLE_DEV_PM_OPS() to make restore() execute the
existing resume() function which will restore the set of RTC.
