SPEAr: Add DT bindings for SPEAr's timer 



All SPEAr SoC's use ST's Timer module. This patch adds device tree probing
capability for that.

* SPEAr ARM Timer



** Timer node required properties:



- compatible : Should be:

	"st,spear-timer"

- reg: Address range of the timer registers

- interrupt-parent: Should be the phandle for the interrupt controller

  that services interrupts for this device

- interrupt: Should contain the timer interrupt number



Example:



	timer@f0000000 {

		compatible = "st,spear-timer";

		reg = <0xf0000000 0x400>;

		interrupts = <2>;

	};
