[PATCH v4 1/2] dt-bindings: iio: light: add Broadcom APDS9999

[Jose A. Perez de Azpillaga]

Add Device Tree binding for the Broadcom APDS9999 ambient light
and proximity sensor. A separate binding file is used rather
than merging with avago,apds9300.yaml because the APDS9999
has an additional vcsel-supply for the VCSEL.

The APDS9999 features individual R, G, B, and IR channels with
a green channel that uses optical coating to approximate the
human eye spectral response for ALS/lux measurements. Calibrated
RGB color sensing is not yet implemented in the driver.

+description: |
+  Broadcom APDS-9999 is a digital proximity and RGB sensor with
+  ambient light sensing (ALS) capability. The device uses individual
+  R, G, B, and IR channels plus a Vertical Cavity Surface Emitting
+  Laser (VCSEL) for proximity detection.
