[Mesa-dev] [PATCH] anv: Implement VK_EXT_pci_bus_info

[Jason Ekstrand]

This is trivial for us to implement because Intel integrated GPUs have
always been at 0000:00:02.0.  One of these days, when we actually ship a
discrete GPU, we'll have to implement it for real but right now we can
just hard code it.
