On MP3,1 with UGA there is a dangling UGA protocol with 1024x768
resolution on ConOut, which points nowhere when no Apple GPU is
installed. Installing GOP on it results in black screen due to
the wrong GOP being chosen for ConOut.

The workaround is not to install the GOP without AppleFramebufferInfo
but this is only applicable to Apple machines, thus the option.

This quirk provides correct TSC and FSB to the kernel, as well as disable topology validation checks. Both of these are required for Hyper-V.
