Yup, although I think for pretty much all hardware the decision about
which DMA driver to use is going to be fixed by silicon consideratons
(eg, in the i.MX case it'd be odd to want to use the FIQ driver when
{S,}DMA support is available) so it probably does make sense for the
DAIs to be able to provide at least a default DMA controller.
