qdev: update pci device registration.

Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch of parameters. Also adds config_read and config_write callbacks to PCIDeviceInfo, so drivers needing these can be converted to the qdev device API too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
