mtd: nand: Sync with Linux v4.6

Browse source 
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.
