[PATCH v2 3/8] mtd: atmel_nand: Use of_device_get_match_data

[Romain Izard <romain.izard.pro-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Remove the need for forward declaration and the risk for a null pointer
when accessing the private part of the compatible match table, by using
the newly introduced of_device_get_match_data function.
