Aseda Aboagye 02e4c2ea9a ppc: sn5s330: Add interrupt handler. ...

Right now, the only events that are unmasked by default are overcurrent
conditions on PP1.  This commit adds a simple interrupt handler and
introduces a board specific callback when the overcurrent status changes
on a port.  This way, a board can take whatever action it desires with
the notification.

BUG=b:69139844
BRANCH=None
TEST=Flash zoombini with SN5S330 stuffed.  Verify that board boots okay.
TEST=With some extra code to setup the interrupt handler, attempt to
exceed the current limit set, verify that interrupt handler is called.
Reduce the current pulled to under the current limit, verify that the
condition is no longer present.
