This patch contains following modifications:
- Add mesh capabilities on fw.c to permit creation of mesh
  interfaces using this driver.
- Modify carl9170_set_operating_mode, to use AP-style beaconing
  with mesh interfaces.
- Allow beacon updates for NL80211_IFTYPE_MESH_POINT type in
  carl9170_handle_command_response.
- Add NL80211_IFTYPE_MESH_POINT case on carl9170_op_add_interfaces to
  support mesh/ap/sta virtual interface combinations.
