When a PCI host bridge description in the DSDT has a missing _BBN or the
_BBN is 0, check if the _ADR field is also 0. If it is, assume that the _BBN really should be 0. Otherwise, try to extract the _BBN from the bridge itself using pchb logic and panic only, if that fails as well. Reported and tested by Martin Husemann as interrupt issue.
