ASoC: wm8741: Drop misleading readable_reg callback implementation
regmap_readable() returns false if map->format.format_write is set. For .reg_bits = 7, .val_bits = 9, setting, map->format.format_write = regmap_format_7_9_write; Even current code has implemented map->readable_reg, regmap_readable() still returns false anyway. Thus drop the misleading readable_reg callback implementation.
