hw/isa/piix4: Replace some magic IRQ constants 

This is a follow-up on patch "malta: Move PCI interrupt handling from
gt64xxx_pci to piix4". gt64xxx_pci used magic constants, and probably
didn't want to use piix4-specific constants. Now that the interrupt
handing resides in piix4, its constants can be used.
