[Qemu-devel] [PATCH 1/8] qdev: update pci device registration.

[Gerd Hoffmann <kraxel@redhat.com>]

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.
