MTD updates #2 for 4.3-rc1: 

* SPI NOR: bug fix for a "end of table" check that resulted in a NULL
    dereference in some cases
 
  * SPI NOR: a few new IDs / feature flags
 
  * OMAP2 NAND: rename module so it doesn't conflict with onenand omap2.ko

Pull more MTD updates from Brian Norris:
 "There was one significant bug in my first pull request, fixed here.  I
  also threw in a few trivial ID additions and a small module rename.

  Details:

   - SPI NOR: bug fix for a "end of table" check that resulted in a NULL
     dereference in some cases

   - SPI NOR: a few new IDs / feature flags

   - OMAP2 NAND: rename module so it doesn't conflict with onenand
     omap2.ko"
