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.
