Subject: [PATCH 2/2] OMAP3: wdtimer: Fix CORE idle transition

From: Paul Walmsley <paul@pwsan.com>

The HW superwised smart idle for wdtimer in OMAP3 prevents
CORE power domain idle transitions. Disable it by swithing
to SW supervised transitions.

This could be a hardware bug in the OMAP3 wdtimer2 block.
