Alexander Graf 9e2c12988b PPC: e500: pci: Export slot2irq calculation
We need the calculation method to get from a PCI slot ID to its respective
interrupt line twice. Once in the internal map function and once when
assembling the device tree.

So let's extract the calculation to a separate function that can be called
by both users.
