The changes I posted earlier for dealing with the MCS1850 RTC (including
a fix suggested by Timm Wetzel) have been committed to HEAD (thanks
christos).  However, there still seems to be some problems writing to the
counter registers.  Writing to RTC_CNTR3 (the LSB) works fine but any
attempts to write to the other three counter registers only seems to
invert the previously stored value.  Here is a patch to enable (and fix)
the debug code - I'm interested to hear if others experience the same
behavior.

Thanks,
Cory.
