I am so glad we split this. Without visual validation check we wouldnt 
have caught the issues and would have ended up with a blank half screen 
on our sc7280 CBs on DP.

For sc7280, I validated the foll cases:

1) Basic Chrome UI comes up
2) Validated some browser use-cases and played some youtube videos
3) Validated multiple plug-in/plug-out cases with DP connected
4) IGT test cases with DP connected:
	- kms_atomic
	- kms_atomic_transition
	- kms_pipe_basic_crc

Some notes:

1) I wanted to test 4k with this too but my monitor only supports 4k at 60 
which is not possible with 24bpp with 2 lanes and due to the HBR3 black 
screen issue I could not test that so far. But since I have that issue 
even with 1080P and without these changes, it should have no effect due 
to this series.

2) I wanted to test some YUV overlay cases but I still cannot find one 
on chrome. Its always using RGB. Will check with others.

With these two noted, this change and this series has my

Tested-by: Abhinav Kumar <quic_abhinavk at quicinc.com>

Only for sc7280 device.

I still cannot give my R-b on this change till others validate visually 
and ensure things arent broken for them.

If we don't get enough validation and if only sc7280 remains in this 
change, please re-post it with only that and I will give my R-b too.
