As per the suggestion of Thierry Reding rename
HDMI_AUDIO_CODING_TYPE_EXT_STREAM to HDMI_AUDIO_CODING_TYPE_EXT_CT to
be consistent with the CEA-861 spec.

When receiving video it is very useful to be able to unpack the InfoFrames.
Logging is useful as well, both for transmitters and receivers.
Especially when implementing the VIDIOC_LOG_STATUS ioctl (supported by many
V4L2 drivers) for a receiver it is important to be able to easily log what
the InfoFrame contains. This greatly simplifies debugging.

Add new Video InfoFrame colorspace information introduced in HDMI 2.0
and new Audio Coding Extension Types, also from HDMI 2.0.
HDMI_CONTENT_TYPE_NONE was renamed to _GRAPHICS since that's what
it is called in CEA-861-F.

Thierry created such nice kerneldocs, it's a shame we've left them
lingering!
For the fun of it also add a bit of kerneldoc to the header so that we
can also include that. Just in case someone adds kerneldoc in there.

HDMI_IDENTIFIER was felt too generic, rename it to what it is, the IEEE
OUI corresponding to HDMI Licensing, LLC.

We just got rid of the version of hdmi_vendor_infoframe that had a byte
array for anyone to poke at. It's now time to shuffle around the naming
of hdmi_hdmi_infoframe to make hdmi_vendor_infoframe become the HDMI
vendor specific structure.

With this last bit, hdmi_infoframe_pack() is now able to pack any
infoframe we support.
At the same time, because it's impractical to make two commits out of
this, we get rid of the version that encourages the open coding of the
vendor infoframe packing. We can do so because the only user of this API
has been ported in:

We'll need the HDMI OUI for the HDMI vendor infoframe data, so let's
move the DRM one to hdmi.h, might as well use the hdmi header to store
some hdmi defines.
(Note that, in fact, infoframes are part of the CEA-861 standard, and
only the HDMI vendor specific infoframe is special to HDMI, but
details..)

Provide the same programming model than the other infoframe types.
The generic _pack() function can't handle those yet as we need to move
the vendor OUI in the generic hdmi_vendor_infoframe structure to know
which kind of vendor infoframe we are dealing with.

To set the active aspect ratio value in the AVI infoframe today, you not
only have to set the active_aspect field, but also the active_info_valid

_valid bit. This was fixed in:
