To run SMP together with DT we need to use emev2_map_io
on EMEV2. This due to some early requirements for ioremap().
Instead of blindly applying this I believe we should spend
time looking into why the common ARM ioremap() code dies
early instead of behaving sanely and returning NULL.
So for now I prefer not to merge this. Anyone wanting
to use and/or develop code for KZM9D can instead make
use of the code in board-kzm9d.c.
