[PATCH v2 13/62] mtd: rawnand: diskonchip: Stop using nand_release()

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().

Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.
