After discussing with Boris, he convinced me that the changes should
be done in another order. That's why first I update the nand_ecc_algo
enumeration in raw NAND, then I introduce the new bindings and the ECC
core itself. Only after that, I patch the raw NAND core (and slightly
SPI-NAND) to share the generic data with the NAND core/ECC framework.

Changes in v10:
* After reworking the entire series, I only kept 4 patches aside,
  resending all of them.
* Fixed typos, updated commit logs as proposed.
* Introduced nanddev_set_ecc_requirements().
* Used spaces instead of tabs in an array.
* Renamed the nand_ecc_is_strong_enough() helper.
* Dropped the use of the MAXIMIZE flag in denali.c.
* Renamed this flag MAXIMIZE_STRENGTH.
* Renamed the of_get_nand_ecc_config*() helpers.

Changes in v9:
* This time sending the additional patchs, not just the old ones with
  corrections. v8 should be ignored, sorry for the noise.

Changes in v8:
* Split "Convert generic NAND bits to ECC framework" into several peaces:
  > added two helpers
  > converted SPI-NAND then raw-NAND.
* Fixed a comment.
* Used the _ooblayout suffix instead of _layout.
