mtd: introduce mtd_has_oob helper
We are working in the direction of making sure that MTD clients to not use 'mtd->func' pointers directly. In some places we want to know if OOB operations are supported by an MTD device. Introduce 'mtd_has_oob()' helper for these purposes. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
