Patch v2:
---------
- sperate patches into 3.
- refine DT bindings documentation about NFC and ECC compatible.
- use ecc->devdata->encode_parity_reg0 and ecc->devdata->err_mask
  directly, but hide them in define.

Tests:
------

* ubifs and jffs2 are validated on NAND device MT29F16G08ADBCA
  by 'dd' command.
* all drivers/mtd/tests/* pass.
* speed test:
  eraseblock write speed is 8318 KiB/s
  eraseblock read speed is 11374 KiB/s
  page write speed is 8155 KiB/s
  page read speed is 11290 KiB/s
  2 page write speed is 8217 KiB/s
  2 page read speed is 11354 KiB/s
  erase speed is 116472 KiB/s
  2x multi-block erase speed is 352978 KiB/s
  4x multi-block erase speed is 359750 KiB/s
  8x multi-block erase speed is 361484 KiB/s
  16x multi-block erase speed is 364116 KiB/s
  32x multi-block erase speed is 364116 KiB/s
  64x multi-block erase speed is 364116 KiB/s
