159f4157b5 pci: apple: Add support for M2 Pro/Max 
The PCIe controller on the M2 Pro/Max is different from the one
found on earlier Apple SoCs.  Some registers moved and te meaning
of the bits in some other registers changed.  But they are still
similar enough to handle both controllers in the same driver.
