mtd: rawnand: oxnas: Keep track of registered devices
All initialized and registered devices should be listed somewhere so that we can unregister/free them in the _remove() path. This patch is not a fix per-se but is needed to apply three other fixes coming right after, explaining the Fixes/Cc: stable tags. Fixes: 668592492409 ("mtd: nand: Add OX820 NAND Support") Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20200519130035.1883-36-miquel.raynal@bootlin.com
