ASoC: topology: Remove multistep topology loading

In theory topology can be loaded in multiple steps by providing index to
snd_soc_tplg_component_load, however, from usability point of view it
doesn't make sense, as can be seen from all current users loading
topology in one go. Remove the unnecessary parameter.
