Bug Description
[Impact]
Hotplugging different monitors on different ports makes HDMI audio
disappears.
[Fix]
Make sure new EDID is added.
[Test case]
Boot up with a HDMI monitor with audio output, unplug the monitor and
plug another monitor without speaker and without audio jack.
Then plug back the original monitor.
With the patch applied, there's still HDMI audio output from the
original monitor.
[Where problems could occur]
If the EDID is valid, the driver does the correct thing.
If the EDID is invalid, then the driver spends a bit more time setting
up EDID, without doing any harm.
