PCI: designware: Drop pci_fixup_irqs()

Browse source 
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.
