Bridges aren't the only thing that needs to know about VGA, any class
VGA device can register for VGA. This adds infrastructure to PCI to
allow devices to register VGA regions and incorporates the previous
PCI bridge only patch to also make use of this. vfio-pci will also
use the pci_register_vga() interface when attaching VGA devices.
v4: Add common pci_vga_[un]register helpers and convert pci_bridge
v3: pci_bridge only: add comments and enable bits for snooping & alias
v2: pci_bridge only: BRIDGE_CONTROL is 2 bytes

Alex Williamson (2):
pci: Add PCI VGA helpers
pci: Teach PCI Bridges about VGA routing
