New struct omap_globals contains the omap processor specific module bases. Use omap_globals to set the various base addresses to make detecting omap chip type simpler. Also introduce OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS for future multi-omap patches. Signed-off-by: Tony Lindgren <tony@atomide.com>
