mach-ux500: move the DB8500 PRCMU driver to MFD
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.
