Landon J. Fuller 711221efd8 bhndb_pci(4): Implement bridge support for CardBus-attached devices.
- Extend the probe method to accept devclasses that inherit from the pci
   devclass (e.g. cardbus).
 - Some BCM4306-based CardBus adapters appear to advertise 4K SPROM, but
   only the first 2K is mapped into BAR0. We can safely assume that the
   SPROM data fits within the first 2K of the SPROM, rather than rejecting
   the SPROM mapping as invalid.
