The Color Matching Descriptor has been present in USB cameras since
the original version of UVC, but it has never been fully exposed
in Linux.

This change informs V4L2 of all of the UVC colorspace parameters:
color primaries, transfer characteristics, and YCbCr encoding.
videodev2.h doesn't have values for all the possible UVC color settings,
so it is mapped as closely as possible.

bFrameIndex and bFormatIndex can be negotiated by the camera during
probing, resulting in the camera choosing a different format than
expected. v4l2 can already accommodate such changes, but the code was
not updating the proper fields.

Without such a change, v4l2 would potentially interpret the payload
incorrectly, causing corrupted output. This was happening on the
Elgato HD60 S+, which currently always renegotiates to format 1.

As an aside, the Elgato firmware is buggy and should not be renegotating,
but it is still a valid thing for the camera to do. Both macOS and Windows
will properly probe and read uncorrupted images from this camera.

With this change, both qv4l2 and chromium can now read uncorrupted video
from the Elgato HD60 S+.

UBSAN reports a shift-out-of-bounds warning in uvc_get_le_value(). The
report is correct, but the issue should be harmless as the computed
value isn't used when the shift is negative. This may however cause
incorrect behaviour if a negative shift could generate adverse side
effects (such as a trap on some architectures for instance).

Regardless of whether that may happen or not, silence the warning as a
full WARN backtrace isn't nice.

uvc_ctrl_add_info() calls uvc_ctrl_get_flags() which will override
the fixed-up flags set by uvc_ctrl_fixup_xu_info().

uvc_ctrl_init_xu_ctrl() already calls uvc_ctrl_get_flags() before
calling uvc_ctrl_add_info(), so the uvc_ctrl_get_flags() call in
uvc_ctrl_add_info() is not necessary for xu ctrls.

This commit moves the uvc_ctrl_get_flags() call for normal controls
from uvc_ctrl_add_info() to uvc_ctrl_init_ctrl(), so that we no longer
call uvc_ctrl_get_flags() twice for xu controls and so that we no longer
override the fixed-up flags set by uvc_ctrl_fixup_xu_info().

This fixes the xu motor controls not working properly on a Logitech
046d:08cc, and presumably also on the other Logitech models which have
a quirk for this in the uvc_ctrl_fixup_xu_info() function.

To quote the TODO of this driver:

--------------------------------------------------------------
The driver is deprecated and scheduled for removal by the end
of 2020.

In order to prevent removal the following actions would have to
be taken:

- clean up the code
- convert to the vb2 framework
- fix the disconnect and free-on-last-user handling (i.e., add
  a release callback for struct v4l2_device and rework the code
  to use that correctly).
