The recent cmd646 discussions reminded me of this patch I've had sitting in an
old branch for a while.
The DP264 machine is the last remaining user of the deprecated
pci_cmd646_ide_init() init function. Switch it over to using qdev via pci_create()
and then remove the now-unused pci_cmd646_ide_init() function.

Remove the call to pci_cmd646_ide_init() since global device init functions
are deprecated in preference of using qdev directly.

Not this patch problem, but it would be nice to have a TYPE_CMD646_IDE.

Secondary_ide disabled is the default in cmd646_ide_properties[], can
we avoid this call?

Yeah - there are quite a few places where this could be improved, but certainly a
patch for another day.

Sure. The patch in its current form is a very simple like-for-like conversion, but it
can be easily be removed.
If we're going to do this then another thing to consider is if we want to replace the
-1 in pci_create() with a specific PCI_DEVFN value to make things a bit more robust.
ATB,
Mark.
