Subject: [PATCH v3 1/6] media: dt-bindings: mediatek,vcodec: Allow single clock for mt8183

MT8173 and MT8183 have different clocks, and consequently clock-names.
Relax the number of clocks and set clock-names based on compatible.

Changes in v3:
- Reintroduced this commit from v1 since the active clock is no longer
  used.
- Further constrained clocks as suggested in v1.
