[RFT PATCH v2 34/42] PCI: designware-host: Drop pci_fixup_irqs()

[Lorenzo Pieralisi]

Since, through struct pci_host_bridge.map/swizzle_irq hooks, IRQs
are now allocated in the pci_assign_irq() callback automatically,
PCI host bridge drivers can stop relying on pci_fixup_irqs()
for IRQ allocation.

Drop pci_fixup_irqs() usage from PCI designware host bridge driver.
