[Intel-gfx] HDMI 4k modes VIC

[Sharma, Shashank]

Actually we should update the cea_modedb in drm layer with 4k modes and appropriate VIC, coz the AVI infoframe functions are
not getting proper VICs for cea modes. Or while processing alternative cea modes, we should check and return VICs. 

I was planning to add 4k at 60 modes, I will probably add one patch there, for handling the 4k modes in CEA db. 
As per CEA-861-F compliance, the 4k at 30 and 4k at 60 modes can come in cea DB as SVD modes. So we should have VICs for them also. 
We will also start upstreaming the patches we added for VLV/CHV, for handling aspect ratio support in libdrm layer as well as kernel.

Shashank

That one looks different, we don't do aspect ratio on modes very well, not even exposing them to user space.
