Ezequiel Garcia b3a23db0e2 media: cedrus: Use H264_SCALING_MATRIX only when required 
Baseline, Main and Extended profiles are specified to
not support a scaling matrix. Also, High profiles
can optionally specify a scaling matrix, using
SPS and PPS NAL units.

To meet this expectation, applications are required to
set the V4L2_CID_MPEG_VIDEO_H264_SCALING_MATRIX control
and set the V4L2_H264_PPS_FLAG_SCALING_MATRIX_PRESENT
flag only when a scaling matrix is specified for a picture.

Implement this on cedrus, which has hardware support for this
case.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
