It's currently broken as it uses an incorrect shift, it tries
to use the slot number but uses the top bits of the bus number
instead.
Note: Neither implementation matches what OpenBIOS ends up putting
in the device-tree either, which will have to be fixed separately.
This is not quite correct for modelling a real Mac since Apple
tend to tie all 4 interrupt lines of a slot together and have
separate interrupts for every slot and every motherboard devices
going straight to the PIC but we'll sort that out later.

Use Coccinelle script to replace 'ret = E; return ret' with
'return E'. The script will do the substitution only when the
function return type and variable type are the same.
Manual fixups:
* audio/audio.c: coding style of "read (...)" and "write (...)"
* block/qcow2-cluster.c: wrap line to make it shorter
* block/qcow2-refcount.c: change indentation of wrapped line
* target-tricore/op_helper.c: fix coding style of
"remainder|quotient"
* target-mips/dsp_helper.c: reverted changes because I don't
want to argue about checkpatch.pl
* ui/qemu-pixman.c: fix line indentation
* block/rbd.c: restore blank line between declarations and
statements

Darwin/OS X use the undocumented kMacRISCPCIAddressSelect (0x48) to
configure PCI memory space size for mac99 machines. Without this
register, warnings similar to below are emitted to the console during boot:
AppleMacRiscPCI: bad range 2(80000000:01000000)
AppleMacRiscPCI: bad range 2(81000000:00001000)
AppleMacRiscPCI: bad range 2(81080000:00080000)
Based upon the algorithm in Darwin's AppleMacRiscPCI.cpp driver, set the
kMacRISCPCIAddressSelect register so that Darwin considers the PCI
memory space to be at 0x80000000 (size 0x10000000) which matches that
currently used by QEMU and OpenBIOS.

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.

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.

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.
