PCIDeviceClass and PCIDevice are defined in pci.h. Many users of the header don't actually need them. Similar structs live in their own headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h, PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and PCIESlot in pcie_port.h. Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with the code that needs them. Adjust include directives. This also enables the next commit.
