Lionel CHAZALLON cfcee4cfe7 Add DRM_PRIME Format Handling and Display for RockChip MPP decoders
This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced
format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor
struct.

That struct holds dmabuf fds and information allowing zerocopy rendering
using KMS / DRM Atomic.

This has been tested on RockChip ROCK64 device.
