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

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

[Rob Herring (Arm)]

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.
