mtd: nand: Force omap_elm to be built as a module if omap2_nand is a module
This commit adds a hidden option to build the omap_elm as a module, if
omap2_nand is a module (and similarly in the built-in case).
This fixes the following build error when omap2_nand is chosen built-in,
and omap_elm is chosen as a module:
drivers/built-in.o: In function `omap_nand_probe':
drivers/mtd/nand/omap2.c:2010: undefined reference to `elm_config'
drivers/mtd/nand/omap2.c:1980: undefined reference to `elm_config'
drivers/mtd/nand/omap2.c:1927: undefined reference to `elm_config'
drivers/built-in.o: In function `omap_elm_correct_data':
drivers/mtd/nand/omap2.c:1444: undefined reference to `elm_decode_bch_error_page'
