'Headphone Switch' control is already registered from
sound/soc/codecs/wm_hubs.c:479, so duplicating it in midas_wm1811
causes following probe failure:

midas-audio sound: control 2:0:0:Headphone Switch:0 is already present
midas-audio sound: ASoC: Failed to add Headphone Switch: -16
midas-audio sound: Failed to register card: -16
midas-audio: probe of sound failed with error -16

Fix this by dropping duplicated control.
