platform/x86/intel/vsec: Assign auxdev parent by argument

Instead of checking for a NULL parent argument in intel_vsec_add_aux() and
then assigning it to the probed device, remove this check and just pass the
device in the call. Since this function is exported, return -EINVAL if the
parent is not specified.
