Add PCI vendor IDs found in ath and mt76 drivers. This should make it
easier for me and others not having to re-define them locally.

brcm80211 include pci_ids.h directly while historically we were tracking
IDs in pci.h. Move the current set of IDs from pci.h to pci_ids.h and
while here add IDs for Realtek and Broadcom as well as a network class
as needed by their wireless drivers.
We still include pci_ids.h from pci.h so this should not change anything.
