PCI: aardvark: Move to struct pci_host_bridge IRQ mapping functions
struct pci_host_bridge gained hooks to map/swizzle IRQs, so that the IRQ mapping can be done automatically by PCI core code through the pci_assign_irq() function instead of resorting to arch-specific implementation callbacks to carry out the same task which force PCI host bridge drivers implementation to implement per-arch kludges to carry out a task that is inherently architecture agnostic. Commit 769b461f ("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.
