hw/display/virtio-vga: Convert TYPE_VIRTIO_VGA_BASE to 3-phase reset

Browse source 
Convert the TYPE_VIRTIO_VGA_BASE class to 3-phase reset, so we
don't need to use device_class_set_parent_reset() any more.

Note that this is an abstract class itself; none of the subclasses
override its reset method.
