There are systems that control LED via COEF instead of GPIO, and to support those systems, move the LED class registration to snd_hda_gen_add_micmute_led(), so all systems can facilitate the same interface. In addition to that, add LED_CORE_SUSPENDRESUME flag since some systems don't restore the LED properly after suspend.
