The SPRD_RTC_POWEROFF_ALM_FLAG flag is used to indicate if a poweroff alarm is set, which can power on the system when system in power-off status. And the bootloader will validate this flag to check if the booting mode is alarm booting mode, thus we should not clear this flag in kernel, instead bootloader will clear this flag after checking the booting mode.
