[GIT PULL FOR v4.19] cec/cec-gpio: add support for 5V testing

[Hans Verkuil]

Some displays disable CEC if the HDMI 5V is not detected. In order
to test issues related to this you want to be able to optionally
detect when the 5V line changes in the cec-gpio driver.

This patch series adds support for this feature.

Regards,

	Hans
