    wifi: mt76: add flexible polling wait-interval support
    
    [ Upstream commit 35effe6c0c24adcf0f732bb1c3d75573d4c88e63 ]
    
    The default waiting unit is 10ms and the value is too much for
    data path related control. Provide a new API mt76_poll_msec_tick()
    to support different cases, such as 1ms polling waiting kick.
