[0/2] RK3288 VP8 decoding support

Message

This patchset adds support for Hantro G1 VP8 stateless decoding,
as available on RK3288 SoC.

In order to support VP8 stateless decoding, a new pixel format
is introduced V4L2_PIX_FMT_VP8_FRAME, to be used with a new control
V4L2_CID_MPEG_VIDEO_VP8_FRAME_HDR.

The VP8 stateless uAPI was submitted as an RFC. The changes
in this v1 are:

Changes from RFC:
* Verify the various ABIs.
* Move entropy coder state fields to a struct.
* Move key_frame field to the flags.
* Remove unneeded first_part_offset field.
* Add documentation.

The ABI has been verified with Maxime Ripard's tools:
