arm nomadik: allow Nand and OneNand to coexists
The evaluation kit has both Nand and OneNand, both drivers are there and the two configurations only select a different default for the jffs partition. This adds the OneNand driver and cleans up storage. Signed-off-by: Alessandro Rubini <rubini@unipv.it> Acked-by: Andrea Gallo <andrea.gallo@stericsson.com>
