edid: Added support for 4k@60 Hz monitor

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.
