Log:
  [ath_hal] add in locationing timer support and capabilities.
  
  * add support to read the timer and capability
  * add support to enable/disable the location timer.
  
  On AR9380 at least, enabling the location timer is required to make
  the timer tick, otherwise location packets return a timestamp of 0.
  However, it then makes /all/ RX packets use the RX location timestamp
  instead of the TSF timestamp.
  
  So, unless I find another magical way to do location timestamping,
  we will have to dynamically switch things on/off and ensure the
  TX/RX path handles the "different" timestamps correctly.
  
  Tested:
  
  * AR9380, STA mode
