mtd: omap2: allow bulding as a module
commit 930d800bded771b26d9944c47810829130ff7c8c upstream. The omap2 nand device driver calls into the the elm code, which can be a loadable module, and in that case it cannot be built-in itself. I can see no reason why the omap2 driver cannot also be a module, so let's make the option "tristate" in Kconfig to fix this allmodconfig build error: ERROR: "elm_config" [drivers/mtd/nand/omap2.ko] undefined! ERROR: "elm_decode_bch_error_page" [drivers/mtd/nand/omap2.ko] undefined!
