Updates the NAND code to match Linux v4.6. The previous sync was from
Linux v4.1 in commit d3963721d9.
Note that none of the individual NAND drivers tracked Linux closely
enough to be synced themselves, other than manually applying a few
cross-tree changes.

[backport from linux commit 02f8c6aee8df3cdc935e9bdd4f2d020306035dbe]
This patch merges the BCH ECC algorithm from the 3.0 Linux kernel.
This enables U-Boot to support modern NAND flash chips that
require more than 1-bit of ECC in software.
