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

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.
Hello Yunfei,
as a suggestion, writing the meaning of the "LAT" acronym may also
help to clear some doubts around (please, also do that in the yaml file,
other than the commit description).
Thank you!
Angelo
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
