3.10-stable review patch. If anyone has any objections, please let me know.

From: Pekon Gupta <pekon@ti.com>
commit 980386d2d6d49e0b42f48550853ef1ad6aa5d79a upstream.
Fixes: commit 75d3625e0e86b2d8d77b4e9c6f685fd7ea0d5a96 ARM: OMAP2+: gpmc: add DT bindings for OneNAND
OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and register them platform_device for ONENAND driver to probe later. However this does not happen if generic MTD_ONENAND framework is built as module (CONFIG_MTD_ONENAND=m).
Therefore, when MTD/ONENAND and MTD/ONENAND/OMAP2 modules are loaded, they are unable to find any matching platform_device and remain un-binded. This causes on board ONENAND flash to remain un-detected.
This patch causes GPMC controller to parse DT nodes when CONFIG_MTD_ONENAND=y || CONFIG_MTD_ONENAND=m
