This CL handles the following:
1. Prevents setting of wrong date in tps6591x_rtc_set_time().
For example the following case was not handled in rtc driver:
if hwclock command wanted to set 31/Dec/1999 then our RTC driver was
setting the date to 31/Dec/2099 and later on when hwclock read the
date back it was getting a invalid date.
Also, the hwclock command can only handle date upto the year 2038.
2. Sets STOP_RTC bit to one when the driver is initialized

RTC_WKALM_SET ioctl should do two things:
1. Set alarm value
2. Enable alarm irq
In the current implementation for RTC_WKALM_SET ioctl we are only setting
the alarm value but not enabling the alarm irq and hence the system
is not waking from lp0 state once the set alarm value expiries.
For RTC_WKALM_SET ioctl, alarm->enabled will be set to one from userspace.
So based on this condition we can differentiate between RTC_WKALM_SET &
RTC_ALM_SET and accordingly enable alarm irq.

The month field of tm structure managed by kernel,
expects a value between 0 to 11.
However, TPS6591x RTC month register expects the month
range to be between 1 to 12.
Hence fixing it.

Without this registration, "wakealarm" node doesnot
get created under the sysfs path /sys/class/rtc/rtc0.
This is used for setting RTC alarms using sysfs.
