    radeon: restructure pci ids to avoid effort later
    
    This uses a single file with all the pciids and parameters for radeon
    family and setup in it. I don't run the perl script at build time to avoid
    a perl dependency on build but adding pci ids should be done via the csv file
    with openoffice or gnumeric if possible.
