Shubhi Garg b60b757d9c rtc: fix year calculation in max77851 pmic rtc ...

Add +100 to year only if PMIC does not have separate alarm
enable registers. Since MAX77851 has separate alarm enable register
, MAX77851 RTC supports year calculation from 0..199 so we do not need
to add 100 on reading RTC YEAR register. Currently, default, driver is
adding +100 which is wrong. This change fixes rtc year calculation.
