Define two capture formats V4L2_PIX_FMT_MT2110R and
V4L2_PIX_FMT_MT2110T to support 10bit in mt8195, mt8199 and more.
Getting the size of each plane again when user space set 10bit
syntax to driver.

V4L2_PIX_FMT_MT2110R is used for H264, and V4L2_PIX_FMT_MT2110T
is used for AV1/VP9/HEVC.

patch 1 Add driver to support 10bit
patch 2 Add capture format V4L2_PIX_FMT_MT2110T to support 10bit tile mode
patch 3 Add capture format V4L2_PIX_FMT_MT2110R to support 10bit raster mode

- compared with v2:
- add the compliance test result: Total for mtk-vcodec-dec device /dev/video-dec0: 46, Succeeded: 46, Failed: 0, Warnings: 0
- this patch is based on separate encoder and decoder patch series.
- compared with v1:
- Fix set non sps return -EINVAL issue.
- Driver test pass in mt8195/mt8188 with tast and Youtube.
- Run v4l2 compliance in mt8195/mt8188 pass.
- fluster test as below:
- h264: (JVT-FR-EXT: 29/69  JVT-AVC_V1: 95/135)
- h265: (JCT-VC-HEVC_V1: 142/147)
- vp9 : (VP9-TEST-VECTORS: 1/6  VP9-TEST-VECTORS: 276/305)
- av1 : (CHROMIUM-10bit-AV1-TEST-VECTORS: 22/23   CHROMIUM-8bit-AV1-TEST-VECTORS: 11/13
-        AV1-TEST-VECTORS: Ran 237/239)

- send the first version v1:
- Run 10bit VP9/AV1 fluster test pass.
- Will return error when the 10bit parameter no correctly in function mtk_vdec_s_ctrl.
