[RFT PATCH v2 40/42] PCI: rockchip: Move to struct pci_host_bridge IRQ mapping functions

[Lorenzo Pieralisi]

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 per-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.

Add map/swizzle IRQs hooks to the rockchip PCI host driver to move
the IRQ allocation into core code and stop relying on arch specific
callbacks.
