dt-bindings: timer: Convert img,pistachio-gptimer to DT schema

Convert the ImgTec Pistachio Timer binding to DT schema format. It's a
straight-forward conversion.

-* Pistachio general-purpose timer based clocksource
-
-Required properties:
- - compatible: "img,pistachio-gptimer".
- - reg: Address range of the timer registers.
- - interrupts: An interrupt for each of the four timers
- - clocks: Should contain a clock specifier for each entry in clock-names
- - clock-names: Should contain the following entries:
-                "sys", interface clock
-                "slow", slow counter clock
-                "fast", fast counter clock
- - img,cr-periph: Must contain a phandle to the peripheral control
-		  syscon node.
-
-Example:
-	timer: timer@18102000 {
-		compatible = "img,pistachio-gptimer";
-		reg = <0x18102000 0x100>;
-		interrupts = <GIC_SHARED 60 IRQ_TYPE_LEVEL_HIGH>,
-			     <GIC_SHARED 61 IRQ_TYPE_LEVEL_HIGH>,
-			     <GIC_SHARED 62 IRQ_TYPE_LEVEL_HIGH>,
-			     <GIC_SHARED 63 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&clk_periph PERIPH_CLK_COUNTER_FAST>,
-		         <&clk_periph PERIPH_CLK_COUNTER_SLOW>,
-			 <&cr_periph SYS_CLK_TIMER>;
-		clock-names = "fast", "slow", "sys";
-		img,cr-periph = <&cr_periph>;
-	};
