Well, I don't think it's fair to break boards just because they are not
(yet) converted to DT ... this board was merged before the DT era on ARM.

Anyway even on DT it's broken: before the switch to the common asoc pcm
code, the dma API was misused to let it think that the audio part of the
SoC was doing the bus mastering, while in fact the sdma was doing it.
