Pull MTD updates from Brian Norris:
 "JFFS2:
   - fix a theoretical unbalanced locking issue; the lock handling was a
     bit unclean, but AFAICT, it didn't actually lead to real deadlocks

  NAND:
   - brcmnand driver: new driver supporting NAND controller found
     originally on Broadcom STB SoCs (BCM7xxx), but now also found on
     BCM63xxx, iProc (e.g., Cygnus, BCM5301x), BCM3xxx, and more

   - begin factoring out BBT code so it can be shared between
     traditional (parallel) NAND drivers and upcoming SPI NAND drivers
     (WIP)

   - add common DT-based init support, so nand_base can pick up some
     flash properties automatically, using established common NAND DT
     properties

   - mxc_nand: support 8-bit ECC

   - pxa3xx_nand:
     * fix build for ARM64
     * use a jiffies-based timeout

  SPI NOR:
   - add a few new IDs

   - clear out some unnecessary entries

   - make sure SECT_4K flags are correct for all (?) entries

  Core:
   - fix mtd->usecount race conditions (BUG_ON())

   - switch to modern PM ops

  Other:
   - CFI: save code space by de-inlining large functions

   - clean up some partition parser selection code across several
     drivers

   - various miscellaneous changes, mostly minor"
