[PATCHv3 4/6] ARM: OMAP3 PM: Enable IO Wake up

[Tero Kristo]

From: Vishwanath BS <vishwanath.bs at ti.com>

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.
