On omap4 we're missing the mcasp node with it's related "ti,hwmods"

Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.

Can you add the DMA as well:

dma-names = "tx";

The RX of McASP is disabled, no RX DMA request.
