iio: light: opt4060: Reject integration times with a non-zero seconds part

When setting the integration time, opt4060_write_raw() only uses
val2 and ignores val. As a result, a write such as 1.000600 is
accepted and programmed as 600 us, silently discarding the whole
seconds part.

Since all supported integration times are less than one second, any
non-zero val represents an invalid input. Reject such values instead
of silently accepting them.
