During stress test of LPSR using RTC alarm, sometimes
RTC alarm fail to fire, the control register(offset 0x38)
is changed and RTC alarm is disabled, according to
design team, when enter LPSR with programming SNVS
to shutdown PMIC, SNVS need some time to finish power
down process, better to put ARM into wfi during this
