[PATCH v5 5/6] media: dt-bindings: mediatek,vcodec-encoder: Add MT8196

[Irui Wang <irui.wang@mediatek.com>]

Add support for MT8196 video encoder which uses VCP (Video Co-Processor)
for firmware management. Unlike previous platforms that use SCP/VPU, MT8196
requires VCP to load and execute the video encoding firmware, with the
encoder communicating through VCP to perform encoding operations.

Add the "mediatek,mt8196-vcodec-enc" compatible string and introduce
the "mediatek,vcp" property to reference the VCP device, which is
required for MT8196 encoder operation.
