Having the check in a centralized place makes the code a bit cleaner and shorter.
Note: There is a slight semantic change in this patch. soc_probe_aux_dev() will no longer return -EBUSY if the AUX dev has already been probed before. This is fine though since it will simply do nothing in that case and return success.
