[GIT PULL FOR v5.3] cec: various fixes/enhancements

[Hans Verkuil]

Various cec fixes and enhancements.

This includes an API addition: CEC_MSG_FL_RAW. This requires CAP_SYS_RAWIO
and when set skips all sanity checks except some core checks such as checking
the payload length.

This flag is typically used when debugging CEC issues with devices that do
not properly follow the specification.

Regards,

	Hans
