[1/2,SRU,Artful] ALSA: hda - Add HP ZBook 15u G3 Conexant CX20724 GPIO mute leds

From: Jerónimo Borque <jeronimo@borque.com.ar>

BugLink: https://bugs.launchpad.net/bugs/1705586

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.
