[PATCH] arm: Convert sa1111 platform and bus legacy pm_ops to dev_pm_ops

[Shuah Khan]

Convert arch/arm/common/sa1111 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.
