Subject: [PATCH v2 1/8] dt-bindings: media: mediatek: decoder: Add MT8189 mediatek,vcodec-decoder

Add compatible for video decoder on MT8189 platform. Compared with
former ICs, the MT8189 decoder use iommu to instead of smmu, and
use scp architecture, the frequency is only 406MHZ, and cannot reach
more than 700MHZ. At the same time, the decoder supports the vp9
decoding protocol for the first time in single IC.
