ASoC: tlv320aic3x: Add virtual output pin Detection
Purpose of this virtual Detection pin is to keep codec bias on whenever the GPIO or jack detection features are needed. Jack detection needs a mic bias so machine drivers can construct a following route for instance for keeping the path and codec bias on: "Input Jack" -> "Mic Bias xV" -> "Detection" -> detection block inside codec. For the GPIO the machine driver can force the pin on with snd_soc_dapm_force_enable_pin.
