dt-bindings: timer: Convert marvell,armada-370-timer to DT schema 



Convert the Marvell Armada 37x/380/XP Timer binding to DT schema format.
Update the compatible entries to match what is in use.
"marvell,armada-380-timer" in particular was missing.

Marvell Armada 370 and Armada XP Timers

---------------------------------------



Required properties:

- compatible: Should be one of the following

              "marvell,armada-370-timer",

	      "marvell,armada-375-timer",

	      "marvell,armada-xp-timer".

- interrupts: Should contain the list of Global Timer interrupts and

  then local timer interrupts

- reg: Should contain location and length for timers register. First

  pair for the Global Timer registers, second pair for the

  local/private timers.



Clocks required for compatible = "marvell,armada-370-timer":

- clocks : Must contain a single entry describing the clock input



Clocks required for compatibles = "marvell,armada-xp-timer",

				  "marvell,armada-375-timer":

- clocks : Must contain an entry for each entry in clock-names.

- clock-names : Must include the following entries:

  "nbclk" (L2/coherency fabric clock),

  "fixed" (Reference 25 MHz fixed-clock).



Examples:



- Armada 370:



	timer {

		compatible = "marvell,armada-370-timer";

		reg = <0x20300 0x30>, <0x21040 0x30>;

		interrupts = <37>, <38>, <39>, <40>, <5>, <6>;

		clocks = <&coreclk 2>;

	};



- Armada XP:



	timer {

		compatible = "marvell,armada-xp-timer";

		reg = <0x20300 0x30>, <0x21040 0x30>;

		interrupts = <37>, <38>, <39>, <40>, <5>, <6>;

		clocks = <&coreclk 2>, <&refclk>;

		clock-names = "nbclk", "fixed";

	};
