The HDMI CEC specification defines deterministic operands for
User Control Pressed that mute or unmute system audio.
Those being:
- Mute Function for mute on
- Restore Volume Function for mute off
This is different from the operand Mute which is a toggle.
This patch adds tests for these User Control Pressed operands.

Notes:
A patch series has been submitted by Hans Verkuil to add CEC UI command operands
to the cec header in the media tree from which v4l-utils copies it. Once those
patches are applied, another patch will be submitted to leverage the new header
operand macros.
