Subject: [PATCH v3 7/8] dt-bindings: media: Add MT8189 mediatek,vcodec-encoder

Add MT8189 encoder compatible string to distinguish former ICs
MTK's. Compared with MT8196, the maximum resolution of MT8189
encoder is only 4K, and the fps is only 30, which cannot reach
the highest parameter of MT8196: level6.2, 8K@...ps.
Compared with MT8188, the level can only support 5.1, which is less
than 5.2 of MT8188. But the maximum bitrate is 100Mbps, which is twice
that of MT8188. And MT8189 could support NBM mode.
