Fix non-terminated PCI match table in PowerMac IDE

The PCI device table in the powermac IDE driver isn't properly terminated. Depending on how your kernel is linked and other random factors, you can end up with this driver matched against any other PCI device in your system, possibly crashing at boot.

Thanks to Heikki for tracking this down with me, the bug have been there for some time, though it rarely hurts due to luck. In this case, the switch from .22 to .23-rc9 is causing it to show up due to differences in the resulting layout of .data I suppose.

If that can still make it in .23, that would be great. I'll also get it in the various -stable releases.
