omap: Split omap_read/write functions for omap1 and omap2+
Otherwise multi-omap1 support for omap1 won't work as the cpu_class_is_omap1() won't work until the SoC is detected. Note that eventually these will go away, please use ioremap + read/write instead. Signed-off-by: Tony Lindgren <tony@atomide.com>
