[PATCH 13/13] ASoC: topology: Unify code for creating standalone and widget enum control

[Amadeusz Sławiński <amadeuszx.slawinski@xxxxxxxxxxxxxxx>]

Code used to create standalone and widget enum control is same, with
exception that in standalone case dynamic object needs to be registered
and control created directly.
