Add HAL_RX_FILTER_BSSID support (to disable bssid match):

Browse Source 
o add HAL_CAP_BSSIDMATCH to identify parts that have the support for
  disabling bssid match
o honor capability for set/get rx filter
o use HAL_CAP_BSSIDMATCH in driver to decide whether to use the bssid
  match disable or fall back to promisc mode
