media: mediatek: vcodec: Add driver to support 10bit

Adding to support capture formats V4L2_PIX_FMT_MT2110T and
V4L2_PIX_FMT_MT2110R for 10bit playback. Need to get the size
of each plane again when user space setting syntax to get 10bit
information.

V4L2_PIX_FMT_MT2110T for AV1/VP9/HEVC.
V4L2_PIX_FMT_MT2110R for H264.
