Subject: [PATCH v4 08/17] media: mtk-vcodec: separate mtk-vcodec-enc node.

From: Maoguang Meng <maoguang.meng@...iatek.com>

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 seperates the two instance. This is a preparing patch for
adding device_link between the larbs and venc-device. It's mainly for
fixing the problem:
https://lkml.org/lkml/2019/9/3/316

User Call "VIDIOC_QUERYCAP":
H264 Encoder return driver name "mtk-vcodec-enc";
VP8 Encoder return driver name "mtk-venc-vp8.
