ELM hardware engine which is used for ECC error detection, is present on all
latest OMAP SoC (like OMAP4xxx, OMAP5xxx, DRA7xxx, AM33xx, AM43xx). Thus ELM
driver should be moved to common drivers/mtd/nand/ folder so that all SoC
having on-chip ELM hardware engine can re-use it.
This patch has following changes:
- mv arch/arm/include/asm/arch-am33xx/elm.h arch/arm/include/asm/omap_elm.h
- mv arch/arm/cpu/armv7/am33xx/elm.c drivers/mtd/nand/omap_elm.c
- update Makefiles
- update #include <asm/elm.h>
- add CONFIG_NAND_OMAP_ELM to compile driver/mtd/nand/omap_elm.c
and include in all board configs using AM33xx SoC platform.

arch/arm/include/asm/arch-am33xx/omap_gpmc.h and
arch/arm/include/asm/arch-omap3/omap_gpmc.h are almost the same, consolidate
the common parts into a new header.
Introduce a new asm/omap_gpmc.h which defines the command part and pulls in
the architecture specific one.

AM33XX has Error Location Module (ELM) that can be used in conjuction
with GPMC controller to implement BCH codes fully in hardware.
This code is mostly taken from arago tree.
