Modified Files:
        src/sys/dev/ic: mm58167.c

Log Message:
Don't refer garbage in stack.
- An argument of struct timeval *tv passed by todr_gettime(9) is used
  for a return value and it doesn't contain valid data. Don't read it.
- Instead, use getmicrotime(9) to get a "reasonable" (i.e. current) time
  to see expected year value (which is not kept by this device).
- If current time is not valid, assume this is the first todr_gettime(9)
  call from inittodr(9) and use file system time for the "reasonable" year.

Fixes silent hangup after mountroot() on sun2.

XXX: MI todr(9) functions seem to get mangled around year ~22000.
