    LinuxKPI: allow bsddriver name to be set for PCI
    
    Allow a driver to overwrite the bsddriver name (we use for pci and
    for wlan parent devices).  This allows us to to set
    .bsddriver.name in struct pci_driver passed to module_pci_driver()
    and with that set the BSD driver name while retaining the Linux .name
    one.
    
    This is helpful for divers which have different parts depending on
    chipset and with that would change driver names which is highly
    confusing especially for configuration.   One example is an upcoming
    rtw88 driver which would be rtw_8822be or rtw_8822ce depending on
    chipset.
