This series aggressively refactors the PC machine initialization to be more
modelled and less ad-hoc. The highlights of this series are:
1) Things like -m and -bios-name are now device model properties
2) The i440fx and piix3 are now modelled in a thorough fashion
3) Most of the chipset features of the piix3 are modelled through composition
4) i440fx_init is trivialized to creating devices and setting properties
5) convert MemoryRegion to QOM
6) convert PCI host bridge to QOM
The point (4) is the most important one. As we refactor in this fashion,
we should quickly get to the point where machine->init disappears completely in
favor of just creating a handful of devices.
The two stage initialization of QOM is important here. instance_init() is when
composed devices are created which means that after you've created a device, all
of its children are visible in the device model. This lets you set properties
of the parent and its children.
realize() (which is still called DeviceState::init today) will be called right
before the guest starts up for the first time.

Change in v4:
*rebase patchset
Changes in v3:
* fix coding style issues
* fix rebase error
* add changes log
Changes in v2:
* Rebase patch series of i440fx in Anthony's qom-rebase.12 branch to upstream
* convert MemoryRegion to QOM
* convert pci_host to QOM
Anthony Liguori (5):
eliminate piix_pci.c and module i440fx and piix3
convert MemoryRegion to QOM
convert pci-host to QOM
prepare to create HPET, RTC and i8254 through composition
merge pc_piix.c to pc.c
