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:

There are two separate hardware encoder blocks inside MT8173.
Split the current mtk-vcodec-enc node to match the hardware architecture.

MTK H264 Encoder(VENC_SYS) and VP8 Encoder(VENC_LT_SYS) are two
independent hardware instance. They have their owner interrupt,
register mapping, and special clocks.
This patch separates them into two devices. This is a preparing
patch for adding device_link between the larbs and venc-device.
It's mainly for fixing the problem:

MTK H264 Encoder(VENC_SYS) and VP8 Encoder(VENC_LT_SYS) are two
independent hardware instance. They have their owner interrupt,
register mapping, and special clocks.
This patch separates them into two devices. This is a preparing
patch for adding device_link between the larbs and venc-device.
It's mainly for fixing the problem:

MTK H264 Encoder(VENC_SYS) and VP8 Encoder(VENC_LT_SYS) are two
independent hardware instance. They have their owner interrupt,
register mapping, and special clocks.
This patch separates them into two devices. This is a preparing
patch for adding device_link between the larbs and venc-device.
It's mainly for fixing the problem:
