OMAP: Remove OMAP_IO_ADDRESS, use OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS instead

Browse Source 
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.
