This patch adds MPUSS(MPU Sub System) power domain
CSWR(Close Switch Retention) support to system wide suspend.
For MPUSS power domain to hit retention(CSWR or OSWR), both
CPU0 and CPU1 power domains need to be in OFF or DORMANT state,
since CPU power domain CSWR is not supported by hardware

This patch adds the CPU0 and CPU1 off mode support. CPUX close switch
retention (CSWR) is not supported by hardware design.

The CPUx OFF mode isn't supported on OMAP4430 ES1.0

CPUx sleep code is common for hotplug, suspend and CPUilde.
