> Enable on-chip RTC support. The on-chip RTC of this SoC is similar to the
> previous versions of Samsung SoC. So re-use the existing RTC driver with
> applicable call-backs for initialization and IRQ handling.
> Add a separate call-back for disabling RTC since existing '.disable'
> call-backs updates additional bit not valid for RTC of ExynosAutov9.
> 
> Setting and getting hardware clock has been tested using 'hwclock'
> and 'date' utilities.

> Alarm interrupt has been checked with incrementing interrupt count via "cat
> /proc/interrupts | grep rtc" for 10sec wakeup time via "echo +10 >
