[RFC v3 PATCH 0/3] dt: device tree bindings and data for EMIF and DDR

[Aneesh V]

This is an RFC to add new device tree bindings for DDR memories and
EMIF - TI's DDR SDRAM controller. 

The first patch adds bindings for LPDDR2 memories.

Second patch provides the bindings for the EMIF controller.

The final patch provides DT data for EMIF controller instances
in OMAP4 and LPDDR2 memories attached to them on various boards.

Thanks to Rajendra for answering my numerous queries on device tree.

Changes in RFC v3:
* Removed support for DDR3
* Incorporated review comments from Olof
