Merge tag 'at91-dt-late' of git://github.com/at91linux/linux-at91 into next/dt

From Nicolas Ferre:
More DT modifications for AT91. Now that I am sure that
the drivers modification are picked-up by MTD.
Changes the use ECC to hardware ECC (named PMECC) for
SoCs that are using it and their associated Evaluation Kits:
- at91sam9x5-ek
- at91sam9n12-ek

* tag 'at91-dt-late' of git://github.com/at91linux/linux-at91:
  ARM: at91: at91sam9n12: add DT parameters to enable PMECC
  ARM: at91: at91sam9x5: add DT parameters to enable PMECC
