ASoC: tegra: Add Tegra210 based ADX driver
The Audio Demultiplexer (ADX) block takes an input stream with up to
16 channels and demultiplexes it into four output streams of up to 16
channels each. A byte RAM helps to form output frames by any combination
of bytes from the input frame. Its design is identical to that of byte
RAM in the AMX except that the data flow direction is reversed.
This patch registers ADX driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes ADX interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver. It can be enabled in the DT via "nvidia,tegra210-adx"
compatible binding.
