hw/acpi/piix4: use qdev gpio to wire up sci_irq

Browse source 
Introduce piix4_pm_init() instance init function and use it to
initialise the separate qdev gpio for the SCI IRQ.

The sci_irq can now be wired up directly using a qdev gpio instead
of having to set the IRQ externally in piix4_pm_initfn().
