Fix a "black screen" issue with analog connector support in DC.
The Radeon HD 7790 series seems specifically affected.
I recommend backporting the series to 6.19 to avoid regressions.
The series also makes the analog connector support more consistent
with the rest of the DC code base so it doesn't feel like a hack
anymore, ie. it brings analog connectors a bit closer to other
connector types.
Series looks good to me.

I assume Alex Hung or Harry will pull this into the DC promotion testing.
I will send this series to promotion test next week.
Thanks,
Alex
