Markus Armbruster edf5ca5dbe include/hw/pci: Split pci_device.h off pci.h
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.
