Module Name:    src

Modified Files:
        src/sys/dev: clock_subr.h
        src/sys/dev/ic: mc146818.c mk48txx.c
        src/sys/kern: kern_todr.c

Log Message:
Fix some issues around todr_wenable():
- As previously defined, it was not possible to return an error from the
  back-end RTC driver.  Make it a real function so that it can do so.
- Only the mc146818 and mk48txx drivers used it (for historical reasons).
  Centralize the logic for how it's used in kern_todr.c (and make it private
  to that file) for consistency.
