This looks like it's a device which maps a shared DMA controller in the
SoC core into ASoC rather than actual hardware.  Such devices are
usually instantiated automatically from the DAI rather than being
represented in the device tree since they are a Linux internal thing
really - the Tegra and Freescale drivers provide examples of how this
sort of thing can be done.
