This introduces the required bits for supporting HEVC/H.265 both in the
V4L2 framework and the Cedrus VPU driver that concerns Allwinner
devices.

A specific pixel format is introduced for the HEVC slice format and
controls are provided to pass the bitstream metadata to the decoder.
Some bitstream extensions are knowingly not supported at this point.

Since this is the first proposal for stateless HEVC/H.265 support in
V4L2, reviews and comments about the controls definitions are
particularly welcome.

On the Cedrus side, the H.265 implementation covers frame pictures
with both uni-directional and bi-direction prediction modes (P/B
slices). Field pictures (interleaved), scaling lists and 10-bit output
are not supported at this point.

This series is based upon the following series:
* media: cedrus: Add H264 decoding support
* vb2/cedrus: add tag support

Changes since v1:
* Added a H.265 capability to whitelist relevant platforms;
* Switched over to tags instead of buffer indices in the DPB
* Declared variable in their reduced scope as suggested;
* Added the H.265/HEVC spec to the biblio;
* Used in-doc references to the spec and the required APIs;
* Removed debugging leftovers.

Cheers!
