From: "yc.hung" <yc.hung@mediatek.com>
This code is based on top of SOF topic/sof-dev branch and we want to have a review
with ALSA and device Tree communities the it will be merged to SOF tree and then
merged into ALSA tree. It provides two patches, one is for mt8195 dsp clocks related.
Another is for mt8195 dsp dts binding decription.
