psu-ng: Add DEGLITCH_LIMIT, deglitch pgoodFault

While the power supply should not arbitrarily report a PGOOD fault, and
then turn it back off, there is a perception that this is indeed
possible, a glitch of some sort.

To avoid possibly logging an error for an erroneous fault reporting,
make sure the fault is reported more than once before considering it to
be a true fault (deglitch the signal).

Tested:
Real Rainier 2S2U:
  Verify tracing PGOOD faults seen and cleared, no error logged
  Verify PGOOD/OFF error logged when manually set ON_OFF_CONFIG & OPERATION.
  Verify deglitched PGOOD again on restart service (ON_OFF_CONFIG reset).
