    ath79: ZTE MF281: use specific board definition file for qca9888
    
    Using board definition file extracted from stock firmware yields 50%
    throughput improvement in RX direction under iperf3 test.
    Make the device use temporary files from firmware_qca-wireless.git
    temporarily, as well as select the specific variant in the device tree
    files. The device uses same board file as the MF286C.
