OMAP: Remove OMAP_IO_ADDRESS, use OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS instead
Search and replace OMAP_IO_ADDRESS with OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS, and convert omap_read/write into a functions instead of a macros. Also rename OMAP_MPUIO_VBASE to OMAP1_MPUIO_VBASE. In the long run, most code should use ioremap + __raw_read/write instead. Signed-off-by: Tony Lindgren <tony@atomide.com>
