mtd: nand: Provide nand_cleanup() function to free NAND related resources
[ Upstream commit d44154f969a44269a9288c274c1c2fd9e85df8a5 ]
Provide a nand_cleanup() function to free all nand related resources
without unregistering the mtd device.
This should allow drivers to call mtd_device_unregister() and handle
its return value and still being able to cleanup all nand related
resources.
