Uninorth is the mac99 PCI host controller, so add
it to the bridge category.

Stefan Hajnoczi 5863d374a3 uninorth: convert ffs(3) to ctz32() 
It is not clear from the code how a 0 parameter should be handled by the
hardware.  Keep the same behavior as ffs(0) - 1 == -1.

Fix PCI hole size to match that what is found on real hardware.
(OpenBIOS already uses the correct length.)

Markus Armbruster 08c58f92f6 pci-host: Consistently set cannot_instantiate_with_device_add_yet 
Many PCI host bridges consist of a sysbus device and a PCI device.
You need both for the thing to work.  Arguably, these bridges should
be modelled as a single, composite devices instead of pairs of
seemingly independent devices you can only use together, but we're not
there, yet.

Since the sysbus part can't be instantiated with device_add, yet,
permitting it with the PCI part is useless.  We shouldn't offer
useless options to the user, so let's set
cannot_instantiate_with_device_add_yet for them.

It's already set for Bonito, Grackle, i440FX and Raven.  Document why.

Set it for the others: dec-21154, e500-host-bridge, gt64120_pci, mch,
pbm-pci, ppc4xx-host-bridge, sh_pci_host, u3-agp, uni-north-agp,
uni-north-internal-pci, uni-north-pci, and versatile_pci_host.

Alexander Graf 8a0e11045d PPC: Use default pci bus name for grackle and heathrow 
There's no good reason to call our bus "pci" rather than let the default
bus name take over ("pci.0").

The big downside to calling it different from anyone else is that tools
that pass -device get confused. They are looking for a bus "pci.0" rather
than "pci".

To make life easier for everyone, let's just drop the name override.
