Subject: [PATCH v8 13/14] mtd: Add HAS_IOMEM || INDIRECT_IOMEM dependency

The UM arch doesn't have HAS_IOMEM=y, so the build fails because the
functions memcpy_fromio and memcpy_toio are not defined anymore. These
functions are only build for targets which have HAS_IOMEM=y or
INDIRECT_IOMEM=y. So, depend on either of the two.
