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.
