Subject: [PATCH v2 3/3] ALSA: hda/cs8409: Add Speaker Playback Switch for Warlock

Add support for a Speaker Playback Switch, which disables
the Amp connected to cs8409. The Switch is not added
automatically because cs8409 does not have an output amp
for the speaker NID.

Note: This switch uses a different GPIO to Cyborg/Odin variants
