mtd: rawnand: oxnas: Keep track of registered devices

Browse Source 
commit 383fc3f613 upstream.

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: 6685924924 ("mtd: nand: Add OX820 NAND Support")
