[PATCH 1/1] edid: Added support for 4k@60 Hz monitor

[Singh, Satyeshwar]

Previously, the large modes (>1080p) that were generated by Qemu in its EDID

were all 50 Hz. If we provide them to a Guest OS and the user selects

one of these modes, then the OS by default only gets 50 FPS. This is

especially true for Windows OS. With this patch, we are now exposing a

3840x2160@60 Hz which will allow the guest OS to get 60 FPS.
