Historically, this driver tried to choose as big ECC strength as
possible, but it would be reasonable to allow DT to set a particular
ECC strength with "nand-ecc-strength" property.

Going forward, DT platforms should specify "nand-ecc-strength" or
"nand-ecc-maximize" to show the ECC strength strategy explicitly.

If nothing is specified in DT, "nand-ecc-maximize" is implied since
this was the original behavior.  It applies to PCI platforms too.

I'd prefer all the DT changes be in 1 patch, but
