[PATCH v2 5/5] iio: light: tcs3472: move standalone return to default case

Move the trailing 'return -EINVAL' statements at the end of
tcs3472_read_raw() and tcs3472_write_raw() into explicit default:
cases inside the respective switch statements.

This removes the need for a separate return statement after the switch.

No functional change.
