ASoC: dapm: Append "Autodisable" to autodisable widget names

Browse Source 
This makes it a little easier to follow what is happening in debugfs.
Additionally is also useful in facilitating work to add autodisable
muxes because the control name is already used for the mux widget and
thus shouldn't be reused for the autodisable widget.
