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!
