mfd: update DB8500 PRCMU driver

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.
