mfd: prcmu: pass a base and size with the early initcall
This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.
