drivers/rtc/rtc-ds3232.c: fix time range difference between linux and RTC chip
In linux rtc_time struct, tm_mon range is 0~11, tm_wday range is 0~6, while in RTC HW REG, month range is 1~12, day of the week range is 1~7, this patch adjusts difference of them. The efect of this bug was that most of month will be operated on as the next month by the hardware (When in Jan it maybe even worse). For example, if in May, software wrote 4 to the hardware, which handled it as April. Then the logic would be different between software and hardware, which would cause weird things to happen.
