This reverts commit 1a653aa44725668590b36bbe2d7fe4736a69f055 ("ASoC: core: replace aux_comp_list to component_dev_list").

That commit tries to remove card->aux_comp_list, using flagged entries in card->component_dev_list instead.

However, components are added to card->component_dev_list in soc_probe_component(). Before that commit, it traversed card->aux_comp_list and found aux devices added by soc_bind_aux_dev(). After that commit, it traverses card->component_dev_list and finds no aux devices, because soc_probe_component() was not yet called for them.

Thus all aux devices are lost and any setup that needs them no longer works.
