This patch series adds Device tree data for the EMIF
sdram controllers in OMAP5 and LPDDR2 memory devices
in OMAP5-evm board.
Testing:
- Boot tested on OMAP5430 evm.
- Built EMIF as a module.
Changes from v2:
* Rebased on top of
git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git for_3.8/dts
* Addressed few other comments from Benoit.

Memory present for OMAP5-evm is 2GB. But in dts file
it is specified as 1GB. Correcting the same.
