pci: Simplify pci_bus_is_root()
pci_bus_is_root() currently relies on a method in the PCIBusClass.
But it's always known if a PCI bus is a root bus when we create it, so
using a dynamic method is overkill.
This replaces it with an IS_ROOT bit in a new flags field, which is set on
root buses and otherwise clear. As a bonus this removes the special
is_root logic from pci_expander_bridge, since it already creates its bus
as a root bus.
