    iwlwifi: add sysctl to dump PCI IDs/ names / firmware-prefixes
    
    Add a FreeBSD-specifc SYSCTL_PROC to dump the list of
    PCI IDs / name / firmware-prefix which can be post-processed
    for man pages (iwlwifi.4 and iwlwififw.4) or the wiki.
    
    The output still yields duplicates depending on by what information
    you need so one may wants to filter them out (try not to use sort/uniq).
