Commit 769b461fc0c0 ("arm64: PCI: Drop DT IRQ allocation from pcibios_alloc_irq()") was assuming all PCI host controller drivers had been converted to use ->map_irq(), but that wasn't the case: pci-aardvark had not been converted. Due to this, it broke the support for legacy PCI interrupts when using the pci-aardvark driver (used on Marvell Armada 3720 platforms). In order to fix this, we make sure the ->map_irq and ->swizzle_irq fields of pci_host_bridge are properly filled in.
