One more time, this time let's just split it for omap1 and omap2,
at least omap2 still depends on it.. Fixing it is another series.

Subject: [PATCH] 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.
