This started with just dma-ranges parsing consolidation, but has expanded
to converting all host drivers to use pci_parse_request_of_pci_ranges()
rather than devm_of_pci_get_host_bridge_resources(). This series moves
the DT 'dma-ranges' parsing into common helpers utilizing a resource list.
There's no (intended) functional change in this series though I'm also
working on a separate series now in dt/next to improve the handling of
'dma-ranges' and dma masks.

The last patch may need to wait if there's any new users of
devm_of_pci_get_host_bridge_resources.

Only versatile has been tested (on QEMU). The rest is compiled only. A git
branch is here[1].
