nd used the EMMA engine instead. As the DMA
support is most probably unused and broken in its current state, remove
it. EMMA becomes the only supported mode on i.MX27.

This also helps us get rid of another user of the legacy i.MX DMA
support and remove the dependency on ARCH_MX* macros as these are
scheduled for removal.
