ARM: OMAP2/3: Remove OMAP_PRM_REGADDR and OMAP2_PRM_BASE

Remove OMAP_PRM_REGADDR and use processor specific defines instead.

Also fold in a patch from Kevin Hilman to add _OFFSET #defines
for the PRCM registers to be used with the prm_[read|write]_* macros.
These are used extensively in the forthcoming OMAP PM support.

Also remove now unused OMAP2_PRM_BASE.
