ASoC: dt-bindings: mediatek: mt8195: merge mt8195 machine yaml

Because the same binding components can be shared by all codecs
combinations, we only reserve one binding file for mt8195 machine driver
and rename to a generic name.

We use compatible string to separate different codec combination instead
of creating a new binding file for new codec combination.
