Updates binding document since the avc and vp8 hardware encoder in
MT8173 are now separated. Separate "mediatek,mt8173-vcodec-enc" to
"mediatek,mt8173-vcodec-enc-vp8" and "mediatek,mt8173-vcodec-enc".
This patch separates the two devices, it's a preparing patch for adding
device_link between the larbs and venc-device. It's mainly for fixing
the problem:
