commit 3c97be6982e689d7b2430187a11f8c78e573abdb upstream.
I have been fooled by the logic picking the right ECC engine which is
spread across two functions: *init_module() and *_attach(). I thought
this driver was not impacted by the recent changes around the ECC
engines DT parsing logic but in fact it is.
