iio: light: stk3310: relax chipid check warning

In order to allow newer devices which are compatible with existing
sensors, issuing a warning for an unknown chipid indicates that
something has gone wrong with the init process, which isn't ideal.
Swap it with a friendlier info message to get things right.
