Allow the instantation of generic dynamic vfio-platform devices again,
without the need to create a new device-specific vfio type.

This is more or less a partial revert of commit 6f2062b9758ebc64
("hw/arm/virt: Allow only supported dynamic sysbus devices").

v4:
  - s/sysbus/vfio-platform/ in patch description,

v3:
  - Drop RFC state,

v2:
  - Restrict from TYPE_SYS_BUS_DEVICE to TYPE_VFIO_PLATFORM, as
    suggested by Eric Auger.

nit: his last sentence is arguable as before we allowed any sysbus
device dynamic instantiation. I would simply remove it.
