[PATCH 62/62] mtd: rawnand: 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().

Now that all drivers have been converted to do not use nand_release()
anymore, let's remove this helper.
