dt-bindings: timer: Convert snps,arc-timer to DT schema

Convert the Synopsys ARC Local Timer binding to DT schema format. It's a
straight-forward conversion.

-Synopsys ARC Local Timer with Interrupt Capabilities
-- Found on all ARC CPUs (ARC700/ARCHS)
-- Can be optionally programmed to interrupt on Limit
-- Two identical copies TIMER0 and TIMER1 exist in ARC cores and historically
-  TIMER0 used as clockevent provider (true for all ARC cores)
-  TIMER1 used for clocksource (mandatory for ARC700, optional for ARC HS)
-
-Required properties:
-
-- compatible : should be "snps,arc-timer"
-- interrupts : single Interrupt going into parent intc
-	       (16 for ARCHS cores, 3 for ARC700 cores)
-- clocks     : phandle to the source clock
-
-Example:
-
-	timer0 {
-		compatible = "snps,arc-timer";
-		interrupts = <3>;
-		interrupt-parent = <&core_intc>;
-		clocks = <&core_clk>;
-	};
-
-	timer1 {
-		compatible = "snps,arc-timer";
-		clocks = <&core_clk>;
-	};
