Currently ecm is only used in DDR20 workaround.

Strictly speaking, this workaround should apply to all TQM8548, not
only to its variants AG and BE, because it's valid for all CPU
revisions.

I overlooked this, when reviewing the patch "MPC85xx: TQM8548:
workaround for erratum DDR 19 and 20".

But I'm fine with the current code and your patch for now. Currently,
there are no other TQM8548 variants than AG and BE.

Kind regards,
Jens
