[Qemu-ppc] [PATCH for-1.6 v2 2/2] pci-bridge: Move common class initializations to base type

[Andreas Färber]

Set PCIDeviceClass::is_bridge as well as PCIDeviceClass::config_write(),
PCIDeviceClass::exit() and DeviceClass::reset() defaults directly for
TYPE_PCI_BRIDGE (complements f055e96bd4311d287c0e03faec02a1bdbc351925).

This avoids another pci_bridge_config_write() missing somewhere, unless
explicitly overridden.
