This is a prerequisite for converting the driver to the common HDMI 2.0 scrambling infrastructure, which implicitly handles SCDC state recovery through a CRTC reset when the sink reconnects while the display pipeline is active. Note that this does not interfere with the local SCDC state-management implementation, since the driver's scrambler capability has not yet been exposed through the common helpers.
