w1: omap-hdq: support device probing with device-tree 

This driver has no 'compatible' string and so is not found when
using device-tree.

Add one with value to match
		hdqw1w: 1w@480b2000 {
device in omap3.dtsi.

* OMAP HDQ One wire bus master controller
Required properties:
- compatible : should be "ti,omap3-1w"
- reg : Address and length of the register set for the device
- interrupts : interrupt line.
- ti,hwmods : "hdq1w"
Example:
- From omap3.dtsi
hdqw1w: 1w@480b2000 {
compatible = "ti,omap3-1w";
reg = <0x480b2000 0x1000>;
interrupts = <58>;
ti,hwmods = "hdq1w";
