Move some declarations to if_iwmreg.h. Remove iwm_fw_alive(); just call iwm_post_alive() directly. Simplify iwm_mvm_add_sta(). Return timeout error from iwm_apm_init(). Print a message when init (i.e. boot) firmware fails to load. Remove some commented-out code which wouldn't compile anyway. Move iwm_mvm_tx_fifo to if_iwmreg.h to match better where Linux puts it.
