[PATCH 2/3] pci: Make auto-config code a little more robust

On my DS414, some PCI devices return odd values when probing BAR sizes. An obvious case is all-ones response, the Linux driver (drivers/pci/probe.c) catches those explicitly and a comment explains that either bit 0 or bit 1 must be clear (depending on MEM or IO type). Other BARs return e.g.
