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")
