Add PM power_off control to rtc driver, along with this PMIC status
is set to STATUS_OFF to shutdown PMIC if PWR_EN is toggled by RTC
module.
System power off sequence:-
* Set PMIC STATUS_OFF when PMIC_POWER_EN is pulled low
* Enable PMIC_POWER_EN in rtc module
* Set rtc ALARM2 time
* Enable ALARM2 interrupt
These patches were tested on AM335x-Bone.
Changes from v1:
- Incorporated Vaibhav's comments on v1
* Changed the time rollover logic with the help of
rtc-lib APIs
