[GIT,PULL,FOR,v5.5,(v2)] vivid: add metadata capture/output support

This series adds vivid metadata capture and output support. While working on
that it was discovered that the v4l2 core didn't correctly validate the ioctls
in the case of the vivid driver that has a complex mix of V4L2 devices and
various video inputs, each with different properties.

Some other cleanups were also done in that code to simplify the logic and
the ioctl validation for touch devices was also improved.

Many thanks to Vandana for working on this as part of the Linux Kernel
Mentorship Program.

Note: the v4l2-compliance test will fail for the metadata output. To make that
work this patch is needed: https://patchwork.linuxtv.org/patch/59480/

Once this series is merged I'll apply that patch as well to v4l-utils.

Changes in v2:

- Updated the "v4l2:Add vivid metadata doc" patch with new dual license

Regards,

	Hans
