This updates the DB8500 PRCMU driver to the latest version available internally. Nominally we would update the dependent CPUfreq driver at the same time but since that is being moved around in this patch set we postpone that by simply deactivating it for the time being. This is a snapshot of the current PRCMU firmware API as it looks right now. The PRCMU firmware is still subject to change. This also updates the CPUfreq driver to a newer version that will utilize the new API.
