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 Signed-off-by: Stefan Binding <sbinding@opensource.cirrus.com> Link: https://lore.kernel.org/r/20220511100207.1268321-4-sbinding@opensource.cirrus.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
