For WCN7850, it is not enough to distinguish all different chips. Add a new string type which includes bus, chip id, board id, vendor, device, subsystem-vendor and subsystem-device for WCN7850. ath12k will first load board-2.bin and searches in it for the board data with the above parameters. If matched with one board data, ath12k downloads it to firmware. And if not, downloads board.bin instead.
