  ppc/pseries: enable big-endian-framebuffer quirk for bochs-display and virtio-vga
  virtio-vga: implement big-endian-framebuffer property
  virtio-gpu: set physical dimensions for EDID
  spice: get monitors physical dimension
  spice: remove the single monitor config logic
  ui: add getter for UIInfo
  edid: use physical dimensions if available
  edid: fix physical display size computation
  virtio-gpu-3d: fix abnormal display after a warm reboot
