ARM: OMAP2+: gpmc: fix: DT NAND child nodes not probed when MTD_NAND is built as module
commit 6b187b21c92b6e2c7e8ef0b450181c37a3f31681 upstream.
Fixes: commit bc6b1e7b86f5d8e4a6fc1c0189e64bba4077efe0
ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND
OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and
register them platform_device for NAND driver to probe later. However this does
not happen if generic MTD_NAND framework is built as module (CONFIG_MTD_NAND=m).
Therefore, when MTD/NAND and MTD/NAND/OMAP2 modules are loaded, they are unable
to find any matching platform_device and remain un-binded. This causes on board
NAND flash to remain un-detected.
This patch causes GPMC controller to parse DT nodes when
CONFIG_MTD_NAND=y || CONFIG_MTD_NAND=m
