Log:
  [ath_hal] Add setting positioning bit and clear sounding-disable bit.
  
  * If fast_ts is set then the TX timestamp is the fast timestamp, not
    normal TSF.
  * If the TX descriptor has the position bit set then request locationing
    and clear sounding-disable.  This way we (a) get the response with
    the TX timestamp from the location side of things, and (b) we get
    a CSI dump of the response ACK, which we will eventually use in the
    locationing path.
