With the introduction of iomap changes platform init code
fails for emu.c if CONFIG_OMAP3_EMU is selected:

arch/arm/mach-omap2/emu.c:35:8: error:
'L4_EMU_34XX_BASE' undeclared here (not in a function)

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.

Otherwise the wrong initcalls can run.

This enables on-chip tracing components found in omap3xxx.
