We're not going to go hacking drivers to have multiple different DMA
interfaces inside them just because SoC maintainers want their own
private DMA interfaces.  We need to come up with a better solution to
this problem.

As I've said, the reality is that ARM's primecell IP is starting to
appear in multiple different SoCs, so we need to solve this problem
now.
