Add various functionality needed to enable a imx53 low power idle state. This includes adding the imx53 gpc_dvfs clock and making a common imx5_late_init function and initializing all imx53 MACHINE_STATE late_init calls to imx5_late_init.

This has to be rebased against the common clock patches.

Where would you add i.MX53 specific code above? Hint: imx5_init_late is the wrong function name.
