This driver is deeply broken in many ways. Miquèl has cleaned it up by:
- flagging the most hideous parts (where Micron on-die ECC support is
  hardcoded)
- enabling DT support, eg. for reading the ECC configuration
- fixing software ECC support
- aligning the software ECC OOB layout to the rest of the world and
  allow a working interoperability in Linux.

I then added a patch to fix writes when soft ECC is on.
