This patch factors out common implementations patterns to reduce overall
kernel

resources from the DT's
common pci_controller

the pending ARM host-bridge drivers. Is its current form likely to be
acceptable?
I'm happy to update the patch for Thierry's suggestions.

It would probably make sense for all these new PCIe host drivers to be
consistent where possible.
