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.
