Add the initial HAL glue for the spectral analysis support.

Browse Source 
* Finish adding the HAL capability to announce whether a NIC supports
  spectral scan or not;
* Add spectral scan methods to the HAL structure;
* Add HAL_SPECTRAL_PARAM for configuration of the spectral scan logic.

The capability ID and HAL_SPECTRAL_PARAM struct are from Qualcomm
Atheros.
