mtd: nand/onenand: Register mtd device upon device scanning
With this patch the NAND and OneNAND devices are registered in the MTD subsystem and can then be referenced by the mtdcore code (e.g. get_mtd_device_nm()). This is needed for the new "ubi part" command syntax without the flash type parameter (nor|nand|onenand). Signed-off-by: Stefan Roese <sr@denx.de>
