Subject: [PATCH] dt-bindings: interrupt-controller: Convert opencores,or1k-pic to DT schema

Convert the OpenRISC PIC interrupt controller binding to schema
format. It's a straight-forward conversion of the typical interrupt
controller.

-Required properties:
-
-- compatible : should be "opencores,or1k-pic-level" for variants with
-  level triggered interrupt lines, "opencores,or1k-pic-edge" for variants with
-  edge triggered interrupt lines or "opencores,or1200-pic" for machines
-  with the non-spec compliant or1200 type implementation.
-
-  "opencores,or1k-pic" is also provided as an alias to "opencores,or1200-pic",
-  but this is only for backwards compatibility.
-
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source. The value shall be 1.
-
-Example:
-
-intc: interrupt-controller {
-	compatible = "opencores,or1k-pic-level";
-	interrupt-controller;
-	#interrupt-cells = <1>;
-};
