Add Support for OPT3004 Digital ambient light sensor (ALS) with
increased angular IR rejection.

The OPT3004 sensor shares the same functionality and scale range as
the OPT3001. The compatible string is added with fallback support to
ensure compatibility.

v2 -> v3:

- Reverse the order of compatible string

v1 -> v2:                                                                       
                                                                                
- Use fallback mechanism for the OPT3004.                                       
- Drop 2/2 patch from the patch series[1] as per feedback.

And where is any user of this, the DTS? We don't take bindings just
because there is such device out there.

I looked and nothing:
