This option allows the VIA configuration to be controlled between 3
different possible setups: cuda, pmu-adb and pmu with USB rather than ADB
keyboard/mouse.
For the moment we don't do anything with the configuration except to pass
it to the macio device (the via-cuda parent) and also to the firmware via
the fw_cfg interface so that it can present the correct device tree.
The default is cuda which is the current default and so will have no
change in behaviour.

Since the IO address space is fixed to use the standard system IO address
space then we can also use the opportunity to remove the address_space_io
parameter from pci_pmac_init() and pci_pmac_u3_init().
Note we also move the default mac99 PCI bus to the end of the initialisation
list so that it becomes the default destination for any devices specified
via -device without an explicit PCI bus provided.

This enables the device to be made available during the setup of the Old World
machine. In order to pass back the previous set of IRQs we temporarily introduce
a new pic_irqs parameter until it can be removed.
An additional benefit of this change is that it is also possible to remove the
pic_mem pointer used for macio by accessing the memory region via sysbus.

Now that the ESCC device is instantiated directly via qdev, move it to within
the macio device and wire up the IRQs and memory regions using the sysbus API.

macio_escc_legacy_setup() and ppc_heathrow_init() in order to keep checkpatch

The timing register exists on all variants of MacIO IDE, we just
store and return its value.
The interrupts register only exists on KeyLargo but it doesn't
hurt to have it. The lack of this register causes MacOS X to
hangs under some circumstances.
Both are 32-bit only. The HW might support smaller access sizes
but no known OS uses them.
Because the core IDE subsystem doesn't provide us with a way
to query the main (level) interrupt state, nor do we have a way
to know that DBDMA issued a (edge) interrupt, we reflect both
through a private pair of qirq's in order to maintain the
register state.

Currently the aiocb is held within MACIOIDEState, however the IDE core code
assumes that the current actvie DMA aiocb is held in aiocb in a few places,
e.g. ide_bus_reset() and ide_reset().
Switch over to using IDEDMA aiocb to store the aiocb for the current active
DMA request so that bus resets and restarts are handled correctly. As a
consequence we can now use ide_set_inactive() rather than handling its
functionality ourselves.

Mac OS X calibrates a number of frequencies on bootup based on reading
tb values on bootup and comparing them to via cuda timer values.
The only variable we can really steer well (thanks to KVM) is the cuda
frequency. So let's use that one to fake Mac OS X into believing the
bus frequency is tbfreq * 4. That way Mac OS X will automatically
calculate the correct timebase frequency.
With this patch and the patch set I posted earlier I can successfully
run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.
