In the PC machine, the PIT is created in board code to allow it to be
virtualized with various virtualization techniques. So explicitly disable its
creation in the PC machine via a property which defaults to enabled. Once the
PIIX implementations are consolidated this default will keep Malta working

TYPE_PIIX3_PCI_DEVICE was the former base class of the Xen and non-Xen variants
of the PIIX3 ISA device models. It will become the base class for the PIIX3 and
PIIX4 device models, so drop the "3" from the type names.

create it as part of the south bridge.
Note that the ACPI function is optional in QEMU. This is why it gets
object_initialize_child()'ed in realize rather than in instance_init.

Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \

- move the typedefs and #defines above the type check macros
