If you use a flattened device tree, you can avoid the need for
platform data by adding the phandle of the dma engine device to
a property of the mmc driver, along with the channel number inside
of that device. I think that would be the cleanest approach, but
some people still need to be convinced that changing drivers to
use fdt data is the right direction for ARM.

Could we keep the current the approach for now and go to the cleanest
way directly when Grant's dt patches get merged?

Sounds good to me. If you are planning to use device trees anyway,
I don't have a problem with leaving it your way in the meantime.
