iio: light: tcs3472: fix ATIME register write 



The integration time is controlled by the ATIME register only.  However,
this register is written by i2c_smbus_write_word_data() in write_raw().

We actually don't need to write a subsequent register.  So just use
i2c_smbus_write_byte_data() instead.
