Hey,
before I leave. When getting woken up by the modem the PMU somehow has the
SECOND interrupt still cleared and will keep it that way. This patch is just
a band aid to the real problem and will set the interrupt mask when we are
not interested in the second interrupt.

Subject: [PATCH] [pcf50633] Set the SECOND interrupt mask to disable the interrupt
On resume from a modem wakeup it was possible that the SECOND interrupt
remained cleared. If we get a periodic tick and are not watching for keys
and have not been asked to tick periodically then disable the interrupt.
Coldplug should remain the same. The root cause is just shadowed with
this commit.
