Now the ramfb will load 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.
So add a new property ramfb-romfile 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.
