ALSA: hda - fix the mic mute led problem for Latitude E5550
The microphone mute led on the Latitude E5550 can't work. We need to apply DELL_WMI_MIC_MUTE_LED quirk to this machine. The machine uses alc293 codec and already applied the quirk ALC293_FIXUP_DELL1_MIC_NO_PRESENCE through pin_fixup_tbl[]. Here we just let DELL_WMI_MIC_MUTE_LED be chained to ALC269_FIXUP_HEADSET_MODE, then the machine will have these quirks ALC293_FIXUP_DELL1_MIC_NO_PRESENCE--> ALC269_FIXUP_HEADSET_MODE-->ALC255_FIXUP_DELL_WMI_MIC_MUTE_LED.
