Subject: [RFC 1/3] regulator: core: Add over current changed event

From: Axel Haslam <ahaslam@...libre.com>

Regulator consumers may be interested to know when the
over current condition is over.

Add an over currerent "changed" event. The registered useres
for this event can then check the over current flag to know
the status of the over current condition.
