[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.
