[PATCH master] bus: omap-gpmc: allow build with raw NAND support disabled

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

GCC complains about an undefined reference to `of_get_nand_bus_width'
when building the driver with CONFIG_MTD_RAW_NAND disabled.

Fix this by omitting probe of the NAND children when barebox doesn't
have NAND drivers enabled anyway.
