[PATCH] arm: Convert locomo platform and bus legacy pm_ops to dev_pm_ops

From: Shuah Khan
Date: Fri Jul 05 2013 - 18:41:15 EST


Convert arch/arm/common/locomo platform and bus legacy pm_ops to dev_pm_ops.
This change also updates the use of COMFIG_PM to CONFIG_PM_SLEEP as this
platform and bus code implements PM_SLEEP ops and not the PM_RUNTIME ops.
Compile tested.
