[PATCH v2 10/11] hw/isa/piix4.c: create PIIX4_PM device directly instead of using piix4_pm_initfn()

[Philippe Mathieu-Daudé]

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

Now that all external logic has been removed from piix4_pm_initfn() the PIIX4_PM
device can be instantiated directly.
