fwget: improve the pci base script

Browse Source 
When matching "class" only match the class byte and not subclass and
programming interface.
Extend the list of supported classes by network, old, and misc (for no
better names on the latter two).
Extend the list of known vendors for various WiFi NICs.
Add a "pci_fixup_class" as some wireless cards have unexpected PCI
classes set.  In case we cannot find a matching file for the original
try to see if a "fixed up" version exists.  This allows us to avoid
duplicate matching files for the same vendor/driver but different
chipsets.
