ALSA: hda/realtek: Enable HP amp and mute LED on HP Folio 9480m [v3]
This laptop needs GPIO4 pulled high to enable the headphone amplifier,
and has a mute LED on GPIO3. I modelled the patch on the existing
GPIO4 code which pulls the line low for the same purpose; this time,
the HP amp line is pulled high.
v2: Disable the headphone amplifier when no headphone is connected.
Don't disable power savings to preserve the LED state.
v3: Remove headset-specific hooks and code; this is just a headphone.
