iio: light: opt4001: Fix a wrong array iteration limit
In practice it's unlikely anyone would try to set the integration time
to 0 which isn't in the available list and if they did then they would
get index 12 which whilst reserved on the device fits in the field.
However a compiler might get half way through this reasoning and that
might be the cause of
> >> drivers/iio/light/opt4001.c:215:9: error: call to '__compiletime_assert_355' declared with 'error' attribute: FIELD_PREP: value too large for the field
> 215 | reg |= FIELD_PREP(OPT4001_CTRL_CONV_TIME_MASK, chip->int_time);
Even if this isn't the cause, it looks like a bug to me.
