rtc: rtc-sh: fix rtc for out-by-one for the month.
The RMONCNT register, which holds the month in the RTC, takes a value
between 1 and 12 while the tm_mon field in the time structures takes
a value between 0 and 11. This wasn't being taken into account in
rtc-sh resulting in the month being out by one.
eg, on my board during boot the RTC is set to:
RTC is set to Thu Jul 01 09:00:00 1999
but "hwclock -r" immediately after logging in was showing:
