pcidump(8): add missing PCI classes

[Jan Klemkow]

Hi,

this diff adds the missing PCI classes Accelerator and Instrumentation.
Thus, we can replace a few unknown in its output:

-       0x0008: Class: 13 (unknown), Subclass: 00 (unknown),
+       0x0008: Class: 13 Instrumentation, Subclass: 00 (null),

Both Classes have vendor specific APIs.  So, there are no predefined
subclasses.

OK?

bye,
Jan
