iio: light: introduce si1133 



e-mail received from Silicon Lab to confirm that the licensing
isn't a problem.

"
Dear Maxime Roussin-Belanger,

The LUX calculation code only works with Si1133.
As long as the software is used with Silicon Lab's sensor product,
I don't see any problem.

Regards,
Tony
