* Second fixes series initiated because of a rework of the ECC engine
   subsystem. The location of the DT parsing logic got moved, breaking
   several drivers which in fact were not doing the ECC engine
   initialization at the right place. These drivers have been fixed by
   enforcing a particular ECC engine type and algorithm, software
   Hamming, while the algorithm may be overwritten by a DT
   property. This merge request fixes this in the xway, socrates,
   plat_nand, pasemi, orion, mpc5121, gpio, au1550 and ams-delta
   controller drivers.

Pull mtd fixes from Miquel Raynal:
 "Second series of fixes for raw NAND drivers initiated because of a
  rework of the ECC engine subsystem.

  The location of the DT parsing logic got moved, breaking several
  drivers which in fact were not doing the ECC engine initialization at
  the right place.

  These drivers have been fixed by enforcing a particular ECC engine
  type and algorithm, software Hamming, while the algorithm may be
  overwritten by a DT property. This merge request fixes this in the
  xway, socrates, plat_nand, pasemi, orion, mpc5121, gpio, au1550 and
  ams-delta controller drivers"
