Pull MTD updates from Brian Norris:
 "Common MTD:

   - Add Kconfig option for keeping both the 'master' and 'partition'
     MTDs registered as devices.  This would really make a better
     default if we could do it over, as it allows a lot more flexibility
     in (1) determining the flash topology of the system from user-space
     and (2) adding temporary partitions at runtime (ioctl(BLKPG)).

     Unfortunately, this would possibly cause user-space breakage, as it
     will cause renumbering of the /dev/mtdX devices.  We'll see if we
     can change this in the future, as there have already been a few
     people looking for this feature, and I know others have just been
     working around our current limitations instead of fixing them this
     way.

   - Along with the previous change, add some additional information to
     sysfs, so user-space can read the offset of each partition within
     its master device

  SPI NOR:

   - add new device tree compatible binding to represent the
     mostly-compatible class of SPI NOR flash which can be detected by
     their extended JEDEC ID bytes, cutting down the duplication of our
     ID tables

   - misc.  new IDs

  Various other miscellaneous fixes and changes"
