[0/9] media: rkvdec: Add H.264 High 10 and 4:2:2 profile support

Message

This series contains minor fixes and adds H.264 High 10 and 4:2:2 profile
support to the Rockchip Video Decoder driver.

Patch 1 adds profile and level controls.

Patch 2 and 3 fixes two issues when decoding field encoded content. Patch 3
also prepare for changes to step_width in the final patch.

Patch 5 updates the v4l2_format helpers to consider block width and height
when calculating plane bytesperline and sizeimage.

Patch 6 adds two new pixelformats for 10-bit 4:2:0/4:2:2.

Patch 7 change to use bytesperline and buffer height to configure strides.

Patch 8 and 9 adds final bits to support H.264 High 10 and 4:2:2 profiles.

This series depend on the "handle unsupported H.264 bitstreams" series at [1].

To fully runtime test this series you may need drm patches from [2] and
ffmpeg patches from [3], this series and drm patches is also available at [4].
