leds: Add device tree binding for pca9633

Similar to tca6507, we can just parse the standard LED
properties for pca9633.

Tested on a pca9632, which is compatible with pca9633.

+LEDs connected to pca9633 or pca9632
+
+Required properties:
+- compatible : should be : "nxp,pca963x"
+
+Optional properties:
+- nxp,totem-pole : use totem pole (push-pull) instead of default open-drain
+
+Each led is represented as a sub-node of the nxp,pca9633 device.
+
+LED sub-node properties:
+- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
+- reg : number of LED line (could be from 0 to 4)
+- linux,default-trigger : (optional)
+   see Documentation/devicetree/bindings/leds/common.txt
+
+Examples:
+

+        compatible = "nxp,pca9632", "nxp,pca963x";
+        #address-cells = <1>;

+        reg = <0x62>;
