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. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
