Subject: drm/bridge: dw-hdmi: add cec notifier support

Add CEC notifier support to the HDMI bridge driver, so that the CEC
|
||||
part of the IP can receive its physical address.

|
||||
Subject: drm/bridge: dw-hdmi: add better clock disable control
|
||||
|
||||
The video setup path aways sets the clock disable register to a specific
|
||||
value, which has the effect of disabling the CEC engine. When we add the
|
||||
CEC driver, this becomes a problem.
|
||||
|
||||
Fix this by only setting/clearing the bits that the video path needs to.
