Define additional structures to be used by HEVC codecs.
This will allow to provide the needed information to the
hardware block.
Adapt Cedrus driver to use these new structures

So this commit description needs some more information.

See commit d9358563179a7f01f9020ebbe201c7e54ba3af48

    media: uapi: h264: Clean slice invariants syntax elements

which explains why it's OK to move some fields out of the slice control,
and which also explains which fields can be moved.

See 7.4.7.1 General slice segment header semantics, in the H.265 ITU specification.

I believe this v4l2_ctrl_hevc_scaling_matrix change shouldn't be here.
