This can be used to easily identify a specific chip on a system with
multiple chips.
Drivers wanting to support this new label property will benefit from
it without a change. They might want to check in the future that
mtd->name is NULL before assigning a default name to the mtd device.
Other drivers will keep the current behavior, which is to override
mtd->name with their own value.

Changes since v1:
- moved the use of the "label" property from mtd_set_dev_defaults()
to mtd_set_of_node() to let drivers keep control on how mtd->name
is set and allocated.
