Subject: [PATCH v6 2/2] devicetree: Add documentation for UPISEMI us5182d ALS and Proximity sensor

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

+* UPISEMI us5182d I2C ALS and Proximity sensor
+
+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 (adc counts) corresponding to every scale
+- upisemi,upper-dark-gain: tuning factor(4 int and 4 fractional bits - Q4.4) applied when light > threshold
+- upisemi,lower-dark-gain: tuning factor(4 int and 4 fractional bits - Q4.4) applied when light < threshold
+
+Example:
+
+    usd5182@39 {
+                compatible = "upisemi,usd5182";
+                reg = <0x39>;
+                upisemi,glass-coef = < 1000 >;
+                upisemi,dark-ths = /bits/ 16 <170 200 512 512 800 2000 4000 8000>;
+                upisemi,upper-dark-gain = /bits/ 8 <0x00>;
+                upisemi,lower-dark-gain = /bits/ 8 <0x16>;
+    };
