ASoC: Handle edge case on SDCA jack control naming

Charles Keepax <ckeepax@opensource.cirrus.com> says:

Normally the SDCA jack detection controls will be named after the GE
widget that represents the grouping of everything in the topology
controlled by the jack selection. However, in the case that the jack
selection only controls a single widget the control will be named after
the SU widget that implements that. It is rather confusing to have the
jack detection controls change naming scheme between devices. Add a new
widget type, similar to mixer widgets, to force use of the control name
rather than falling back to the widget names.
