Commit 669cbc708122 ("PCI: Move DT resource setup into
devm_pci_alloc_host_bridge()") made devm_pci_alloc_host_bridge() fail on
any DT resource parsing errors, but Broadcom iProc uses
devm_pci_alloc_host_bridge() on BCMA bus devices that don't have DT
resources. In particular, there is no 'ranges' property. Fix iProc by
making 'ranges' optional.
If 'ranges' is required by a platform, there's going to be more errors
latter on if it is missing.

You're great Rob, thank you!
I've tested it on top of the 669cbc708122 and linux-5.10.y.
