Gerd Hoffmann b290659fc3 hw/vfio/display: add ramfb support
So we have a boot display when using a vgpu as primary display.

ramfb depends on a fw_cfg file.  fw_cfg files can not be added and
removed at runtime, therefore a ramfb-enabled vfio device can't be
hotplugged.

Add a nohotplug variant of the vfio-pci device (as child class).  Add
the ramfb property to the nohotplug variant only.  So to enable the vgpu
display with boot support use this:

  -device vfio-pci-nohotplug,display=on,ramfb=on,sysfsdev=...
