mtd: rawnand: arasan: Fix missing de-registration of NAND 



The NAND chip-selects are registered for the Arasan driver during
initialization but are not de-registered when the driver is unloaded. As a
result, if the driver is loaded again, the chip-selects remain registered
and busy, making them unavailable for use.
