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>;
