Pull MTD updates from Brian Norris:
 - A few SPI NOR ID definitions
 - Kill the NAND "max pagesize" restriction
 - Fix some x16 bus-width NAND support
 - Add NAND JEDEC parameter page support
 - DT bindings for NAND ECC
 - GPMI NAND updates (subpage reads)
 - More OMAP NAND refactoring
 - New STMicro SPI NOR driver (now in 40 patches!)
 - A few other random bugfixes
