ALSA: hda/tegra: Add Tegra234 hda driver support
Add hda driver support for the Tegra234 chip. The hdacodec
on this chip now supports DP MST feature, HDA block contains
azalia controller and one hda-codec instance by supporting
4 independent output streams over DP MST mode. There is no
input stream support.
