Hans Verkuil 632b8b044a media: cec: core: count low-drive, error and arb-lost conditions
Count how many Low Drive, Error and Arbitration Lost transmit
status errors occurred, and expose that in debugfs.

Also log the first 8 transmits that result in Low Drive or Error
conditions. That really should not happen with well-behaved CEC devices
and good HDMI cables.

This is useful to detect and debug HDMI cable issues.
