drm/virtio: Add the hotplug_mode_update property for rescanning of modesdrm-qemu-next
Setting this property will allow the userspace to look for new modes or
position info when a hotplug event occurs. This is really helpful for
virtual GPU drivers to handle Host window resizing events which are
propogated as hotplug interrupts to the Guest drivers. Mutter already
uses this property while configuring the outputs.
