[PATCH v1 4/4] of: PCI: tidy up logging of ranges containing configuration space type

From: Daire McNamara <daire.mcnamara@microchip.com>

PCI ranges can contain addresses where phys.high part can have a type
of 0, signifying 'configuration space'. Change
devm_of_pci_get_host_bridge_resources() to print 'CFG' instead of 'err'
for a PCI range containing such a 'configuration space' type.
