This helps validating DTS files. Introduced changes:
1. Reworded title
2. Added required #include-s and adjusted "reg" in example

-Device-Tree bindings for Mediatek consumer IR controller
-found in Mediatek SoC family
-
-Required properties:
-- compatible	    : Should be
-			"mediatek,mt7623-cir": for MT7623 SoC
-			"mediatek,mt7622-cir": for MT7622 SoC
-- clocks	    : list of clock specifiers, corresponding to
-		      entries in clock-names property;
-- clock-names	    : should contain
-			- "clk" entries: for MT7623 SoC
-			- "clk", "bus" entries: for MT7622 SoC
-- interrupts	    : should contain IR IRQ number;
-- reg		    : should contain IO map address for IR.
-
-Optional properties:
-- linux,rc-map-name : see rc.txt file in the same directory.

-Example:
-
