rtc-x1205: reset clock to sane state after power failure

When detecting power failure, the probe function would reset the clock
time to defined state.

However, the clock's _date_ might still be bogus and a subsequent probe
fails when sanity-checking these values.

Change the power-failure fixup code to do a full setting of rtc_time,
including a valid date.
