Tony Lindgren ee0839c22c ARM: OMAP2+: Move most of plat/io.h into local iomap.h
There's no need to have these defines in plat/io.h.

Note that we now need to ifdef omap_read/write calls
as they will be available for omap1 only.

While at it, clean up the includes to group them like
they typically are grouped.
