[PATCH 3/4] ARM: OMAP3 PM: Enable IO Wake up

[Vishwanath BS]

Enable IO Wake up for OMAP3 as part of PM Init.
Currently this has been managed in cpuidle path which is not the right place.
Subsequent patch will remove IO Daisy chain handling in cpuidle path once daisy
chain is handled as part of hwmod mux.
