        src/sys/dev/i2c: m41st84.c m41st84reg.h

Log Message:
Handle the Halt Update Bit (HT), stored in the Alarm Hour register.
This bit will be set if the clock lost power (and may therefore
not have the correct time).  If this bit is set, the stored time
does not advance.  So, when setting the clock, if that bit is set,
we simply clear it.  It might be nice in some applications to pass
the information up a few layers if the bit is set when we read the
register initially.  For now, though, we ignore it.
