[PATCH v3 2/2] devicetree: Add documentation for UPISEMI us5182d ALS and Proximity sensor

[Adriana Reus <adriana.reus@intel.com>]

Added entries in trivial-devices and i2c/vendor-prefixes for
the us5182d als and proximity sensor. Also added a documentation file for
this sensor's properties.

+Required properties:
+- compatible: must be "upisemi,usd5182"
+- reg: the I2C address of the device

+Optional properties:
+- upisemi,glass-coef: glass attenuation factor
+- upisemi,dark-ths: array of thresholds corresponding to every scale
