We have a few more mailboxes and fixed messages in the
DB8500 PRCMU, update to match the latest specification.

Instead of carrying around the __PRCMU_BASE in every read or
write to the PRCMU registers, move it out to the register
definition file and define registers along with their base
offset so that the code gets easier to read.

With the addition of a device platform mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

The DB8500 has ePOD:s (electronic power domains) which are possible
to switch on/off to deactivate silicon blocks on the DB8500 SoC
by cutting their power without retention. We model these as simple
regulators with one bit on/off settings.

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.

We have decided that this function arbiter fits better in the MFD
subsystem. Since we need to concatenate the split header files we move
it basically like this:
mv mach-ux500/prcmu-db8500.c drivers/mfd/db8500-prcmu.c
mv mach-ux500/include/mach/prcmu-defs.h include/linux/mfd/db8500-prcmu.h
mv mach-ux500/include/mach/prcmu-regs.h drivers/mfd/db8500-prcmu-regs.h
mach-ux500/include/mach/prcmu.h >> include/linux/mfd/db8500-prcmu.h
rm arch/arm/mach-ux500/include/mach/prcmu.h
Then we update different #include statements and Makefile orders etc
to make the PRCMU driver compile, link and boot in the new place
without really changing any code.
