Subject: [PATCH v2 05/10] PCI: Replace pr_*() with dev_*() in __of_pci_get_host_bridge_resources()

From: Jan Kiszka <jan.kiszka@...mens.com>

Now that we have a device reference, make use of it for printing. And as
long as dev can still be NULL, we will still get some reasonable output
nevertheless.
