[LV] [RFC] RTC/TOY cleanup: move to new RTC API

Standard operating procedure on VAX/VMS is to run SET TIME at least
once per year.  This command writes the current year to SYS.EXE and
the month/day/etc to the TOY register.  As long as you do a SET TIME
before May the following year, you'll be OK.

In our case, we should probably write the current year to a known
place in the kernel image.

Later,
Kenn
