Refactor parts of the 3COM NIC code
Move the reusable PCI specific parts into pcidev.c, they'll be usable
for other NIC code (Realtek, VIA, ...) and also for SATA/IDE controller
cards as external programmers (for every PCI device which can program
EEPROMs basically).
Also add print_supported_pcidevs() to show the supported PCI devices
(currently only NICs, soon more) in the 'flashrom -L' output.
Corresponding to flashrom svn r515.
