- Fix the device database parsing code so that it actually works.

Browse Source 
- Improve the formatting for devices identified by the database.
 - Fix the pcib_route_interrupt method definition, as an old version
   snuck in here somehow 8(
 - Remove a couple of the vendor/device IDs for PCI:ISA bridges which
   correctly identify themselves.
