Currently only hw ecc is supported in U-Boot. If any other ecc mode is given in DT, it simply ignores and switches to hw ecc. So better print what is being done.
Revert this patch once soft ecc support is fixed in future.

Better to simply not continue if sw ecc is asked. DT can be for Linux itself and U-Boot shouldn't really break data inside it. Printing information about it is IMHO good approach. Pretty much SW ECC is not available - skip driver probe or something like that is nice way how to describe it.
