OMAP3 PM code for off-mode currently saves the scratchpad contents for CM registers within OMAP control module driver. However, as we are separating CM code into its own driver, this must be moved also. This patch adds a new API for saving the CM scratchpad contents and uses this from the high level scratchpad save function.
