ALSA: hda - Add HP ZBook 15u G3 Conexant CX20724 GPIO mute leds
The HP ZBook 15u G3 has a Conexant CX20724 with mute led on GPIO1 and mic mute led on GPIO2. Adding CXT_FIXUP_MUTE_LED_GPIO inspired on patch_realtek's one. Signed-off-by: Jerónimo Borque <jeronimo@borque.com.ar> Signed-off-by: Takashi Iwai <tiwai@suse.de>
