ASoC: topology: Remove unused functions from topology API

Topology API exposes snd_soc_tplg_widget_remove and
snd_soc_tplg_widget_remove_all, but both are nowhere used. All current
users load and unload topology as a whole. As following commits
introduce resource managed memory, remove them to simplify code and
reduce maintenance burden.
