iwlwifi: split firmware API from iwl-trans.h
In order to more clearly document which parts of this file are firmware API and which are something else, split the firmware API into a separate file to include here. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
