move paramater definitions to a device paramater structure only leaving the device name, which antennas are used and what firmware file to use in the iwl_cfg structure. this will not completely remove the redundancies but greatly reduce them for devices that only vary by name or antennas. the parameters that are more likely to change within a given device family are left in iwl_cfg. also separate bt param structure added to help reduce more.
