[PATCH] OMAP: powerdomains: Make all powerdomain target states as ON at init

[Santosh Shilimkar]

From: Rajendra Nayak <rnayak at ti.com>

Program all powerdomain target state as ON; This is to
prevent domains from hitting low power states (if bootloader
has target states set to something other than ON) and potentially
even losing context while PM is not fully initilized.
The PM late init code can then program the desired target
state for all the power domains.
