Subject: PCI MMConfig: Only call unreachable_devices() when type 1 is available.
From: Olivier Galibert <galibert@xxxxxxxxx>
unreachable_devices compares between the results of pci configuration accesses
through type1 and mmconfig, so it should be called only if type1 actually
works in the first place.
