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.

flush_scheduled_work() is deprecated and scheduled to be removed.  On
removal, directly cancel the work, and flush the uie_task in
rtc-dev.c::clear_uie().

The DS3232 RTC driver only has the tick function.  Add an alarm function
so the driver is complete.

A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit. This is obsolete meanwhile, so fix it and hope the word will spread.

Add a driver for the DS3232 RTC chip via the I2C bus.  Alarms are not
supported in this version of the driver.
