This patch fixes 525e05147d5a3bdc08caa422d108c1ef71b584b5 by introducing device specific get_dev_dict callback. pci host bridge doesn't always have header type of bridge.
Especially PBM which is emulated doesn't conform to PCI spec at the moment. So by introducing get_dev_dict, allow each pci device to return specific infos. This patch also makes it easier to enhance info pci command in the future. For example returning pcie stuff. Cc: Blue Swirl <blauwir...@gmail.com> Cc: "Michael S.
