Add basic device tree support for the BSH SMM-M2B SystemMaster,
a hardware variant of the BSH SMM-M2 equipped with an AIC Wi-Fi
and Bluetooth chip.

This series adds the SMM-M2B board compatible to the Freescale
device tree bindings.

Configure the NAND controllers on the BSH SMM-M2 and SMM-S2 to
use the minimum required ECC strength.

Adjust the Wi-Fi and Bluetooth enable pin settings, configure the
WLAN host wake pin with a pull-down, and remove the unused
cap-sdio-irq property.

Move the hardware definitions shared by the SMM-M2 variants into
a common device tree include file to reduce duplication.

Add the SMM-M2B board device tree and Makefile entry, reusing
the common hardware definitions.

Configure the UART2 pin multiplexing for the shared SMM-M2 hardware.

Enable USB OTG mode on the BSH SMM-M2 and SMM-S2 board variants.

Changes in v2:
- Drop the redundant RNGB enablement patch.
- Keep the WLAN power sequence in the SMM-M2-specific DTS.
- Move the SPI display and touchscreen overlay out of this series.
