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.

BusInfo is filled with name and size (pretty much like I did for
DeviceInfo as well). There is also a function pointer to print
bus-specific device information to the monitor. sysbus is hooked
up there, I've also added a print function for PCI.
Device creation is slightly modified as well: The device type search
loop now also checks the bus type while scanning the list instead of
complaining thereafter in case of a mismatch. This effectively gives
each bus a private namespace for device names.

The only purpose DeviceType serves is creating a linked list of
DeviceInfo structs. This removes DeviceType and add a next field to
DeviceInfo instead, so the DeviceInfo structs can be changed that way.
Elimitates a pointless extra level of indirection.

* fix secondary bus setup.
* use base->name instead of "FIXME" for device name.
Yes, the device name is redundant. Only for drivers converted
to qdev already though. Once all drivers are converted we can
and should kill it.
