Now we use the IORESOURCE_STARTALIGN to identify bridge
resources in __assign_resources_sorted(). But there would
be some problems because some PCI devices' resources may
also use IORESOURCE_STARTALIGN, e.g. using "noresize"
option of resource_alignment kernel parameter.
So this patch replaces IORESOURCE_STARTALIGN with
IORESOURCE_WINDOW.
