Adds decoder dt-bindings for compatible "mediatek,mtk-vcodec-lat- soc".

What's lat soc? How does this relate to what's already there in this binding.

lat soc is another hardware, is related with some vdec larb ports. Won't be used to decode, but must to write it in dtsi, or hardware can't work well.

Need to enable clock/power/iommus, no interrupt.

The subject space is limited, avoid saying the same thing twice (dt-bindings).

Best Regards, Yunfei Dong
