Currently the ramfb device loads the vgabios-ramfb.bin unconditionally, but only the x86 need the vgabios-ramfb.bin, this can cause that when use the release package on arm64 it can't find the vgabios-ramfb.bin. Because only seabios will use the vgabios-ramfb.bin, load the rom logic is x86-specific. For other !x86 platforms, the edk2 ships an EFI driver for ramfb, so they don't need to load the romfile. So add a new property use-legacy-x86-rom in both ramfb and vfio_pci device, because the vfio display also use the ramfb_setup() to load the vgabios-ramfb.bin file. After have this property, the machine type can set the compatibility to not load the vgabios-ramfb.bin if the arch doesn't need it. For now the default value is true but it will be turned off by default in subsequent patch when compats get properly handled.
