Decoder will use component framework to manage hardware, it is big
difference with encoder.

-Mediatek Video Codec
-
-Mediatek Video Codec is the video codec hw present in Mediatek SoCs which
-supports high resolution encoding and decoding functionalities.
-
-Required properties:
-- compatible : must be one of the following string:
-  "mediatek,mt8173-vcodec-enc-vp8" for mt8173 vp8 encoder.
-  "mediatek,mt8173-vcodec-enc" for mt8173 avc encoder.
-  "mediatek,mt8183-vcodec-enc" for MT8183 encoder.
-  "mediatek,mt8173-vcodec-dec" for MT8173 decoder.
-  "mediatek,mt8192-vcodec-enc" for MT8192 encoder.
-  "mediatek,mt8183-vcodec-dec" for MT8183 decoder.
-- reg : Physical base address of the video codec registers and length of
-  memory mapped region.
-- interrupts : interrupt number to the cpu.
-- mediatek,larb : must contain the local arbiters in the current Socs.
-- clocks : list of clock specifiers, corresponding to entries in
-  the clock-names property.
-- clock-names: avc encoder must contain "venc_sel", vp8 encoder must
-  contain "venc_lt_sel", decoder must contain "vcodecpll", "univpll_d2",
-  "clk_cci400_sel", "vdec_sel", "vdecpll", "vencpll", "venc_lt_sel",
-  "vdec_bus_clk_src".
-- iommus : should point to the respective IOMMU block with master port as
-  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml
-  for details.
-- dma-ranges : describes the dma address range space that the codec hw access.
-One of the two following nodes:
-- mediatek,vpu : the node of the video processor unit, if using VPU.
-- mediatek,scp : the node of the SCP unit, if using SCP.
