vfio display needs to release the invalid display resource and disable
the scanout mode during guest OS reboot, otherwise bugs come out.

Thanks hang.yuan@intel.com for helping root cause the issue.

v3->v4:
 - Move dma-buf based display check into the vfio_display_reset().
   (Gerd)

v2->v3:
 - Limit vfio_display_reset to dma-buf based vfio display. (Gerd)

v1->v2:
 - remove dpy_gfx_switch_surface. (Gerd)
 - add dpy_gfx_update_full. (Gerd)

Tina Zhang (2):
  console: introduce dpy_gfx_update_full
  ui: introduce vfio_display_reset
