mtd: rawnand: marvell: Use correct logic for nand-keep-config

Originally the absence of the marvell,nand-keep-config property caused
the setup_data_interface function to be provided. However when
setup_data_interface was moved into nand_controller_ops the logic was
unintentionally inverted. Update the logic so that only if the
marvell,nand-keep-config property is present the bootloader NAND config
kept.
