dt-bindings: timer: Convert lsi,zevio-timer to DT schema

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

-TI-NSPIRE timer
-
-Required properties:
-
-- compatible : should be "lsi,zevio-timer".
-- reg : The physical base address and size of the timer (always first).
-- clocks: phandle to the source clock.
-
-Optional properties:
-
-- interrupts : The interrupt number of the first timer.
-- reg : The interrupt acknowledgement registers
-	(always after timer base address)
-
-If any of the optional properties are not given, the timer is added as a
-clock-source only.
-
-Example:
-
-timer {
-	compatible = "lsi,zevio-timer";
-	reg = <0x900D0000 0x1000>, <0x900A0020 0x8>;
-	interrupts = <19>;
-	clocks = <&timer_clk>;
-};
-
-Example (no clock-events):
-
-timer {
-	compatible = "lsi,zevio-timer";
-	reg = <0x900D0000 0x1000>;
-	clocks = <&timer_clk>;
-};
