OneNAND: Fill in MTD function pointers for OneNAND.
onenand_print_device_info(): - Now returns a string to be placed in mtd->name, rather than calling printf. - Remove verbose parameter as it becomes useless. Signed-off-by: Fathi Boudra <fabo@debian.org> Signed-off-by: Scott Wood <scottwood@freescale.com>
