leds: lp55xx: add support for Device Tree bindings
This patch allows the lp5521 driver to be successfully probed and initialised when Device Tree support is enabled. Based on a patch by Gabriel Fernandez, rewritten in accordance with review feedback.

+Binding for National Semiconductor LP55xx Led Drivers
+
+Required properties:
+- compatible: "national,lp5521" or "national,lp5523"
+- label: Used for naming LEDs
+- num-channel: Number of LED channels
+- led-cur: Current setting at each led channel (mA x10, 0 if led is not connected)
+- max-cur: Maximun current at each led channel.
+- clock-mode: Input clock mode, (0: automode, 1: internal, 2: external)
+
+example:
+
+lp5521@32 {
+ compatible = "national,lp5521";
+ reg = <0x32>;
+ label = "lp5521_pri";
+ num-channel = /bits/ 8 <3>;
+ led-cur = /bits/ 8 <0x2f 0x2f 0x2f>;
+ max-cur = /bits/ 8 <0x5f 0x5f 0x5f>;
+ clock-mode = /bits/8 <2>;
+};
