mtd: rawnand: Hide the chip->data_interface indirection
As a preparation for allocating the data interface structure dynamically (and rename it), let's avoid accessing chip->data_interface directly. Instead, we introduce a helper, nand_get_interface_config(), and use it to retrieve the current data interface configuration out of a nand_chip object.
