  1. psc: allow PSUs a grace period before requiring OK after enable. 

    In fault injection testing I've seen _one time_ when the PSU failed to
assert OK quickly after being enabled. This caused us to fault it and
try again, at which point it worked. But, that has the effect of
inserting an additional 5s delay on the fault recovery cycle, which in
theory could repeat forever.

This change adds a grace period after taking a faulted PSU out of fault
status, before we start expecting it to assert OK. This mirrors the
grace period we provide for newly inserted PSUs.
