Pull late MTD fixes from Brian Norris:
 "Another round of MTD fixes for v4.8

  My apologies for sending this so late.  I've been fairly absent as a
  maintainer this cycle, but I did queue these up weeks ago.  In the
  meantime, Richard was able to handle some other fixes (thanks!) but
  didn't pick these up.

  On the bright side, these are very simple changes that should carry
  little risk.


   - Davinci NAND: fix a long-standing bug in how we clear/prep 4-bit ECC

   - OMAP NAND: an error-handling fix that made it into v4.8-rc1 caused
     error-handling cases in other configurations/code-paths; this fixes
     the fix"
