zinger: ensure we re-enable the output once a fault is cleared
When a fault is cleared, reset the PD state and communicate,
so that we re-enable the output and negociate a new voltage.

BRANCH=none
BUG=none
TEST=on Zinger connected to Firefly, trigger an OCP (using an electronic load)
and see that the output is re-enabled once the OCP is cleared after 1 second.
