[GIT PULL FOR v7.3] media: CEC fixes/improvements + doc and vivid fix

[Hans Verkuil]

Hi Mauro,

This PR has one documentation improvement, one fix for vivid, and a bunch of
CEC related fixes and improvements.

Once this PR is merged, I'll also push a separate cec-compliance patch:

https://lore.kernel.org/linux-media/65a6bd5c-4e62-4370-b654-7dce0712aae5@kernel.org/

This uses the vivid CEC emulation and new error injection capability to add
new regression tests.

Regards,

	Hans
