edid: Added support for 4k@60 Hz monitor

Browse Source 
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.
