ARM: OMAP2+: PRCM: split and relocate the PRM/CM globals setup
Split omap2_set_globals_prcm() into PRM, CM, and PRCM_MPU variants, since these are all separate IP blocks. This should make it easier to move the PRM, CM, PRCM_MPU code into drivers/ in future patchsets. At this point arch/arm/plat-omap/include/plat/prcm.h is empty; a subsequent patch will remove it, and remove the #include from all the files that #include it.
