Well, the mandatory requirements here are as follow (AFAIK):
1. keep one binary for all imx6dl imx6[qp|dl|q]-sabresd
2. have DM support in SPL

So I guess we have to either prioritize the other needed configs and
leave out the one we can do without. That, ofcourse, if we still want
to fit in and we still want one binary for all three sabresd boards.
