media: dt-bindings: mt9p031: Convert bindings to yaml

Convert mt9p031 sensor bindings to yaml schema. Also update the
MAINTAINERS entry.

Although input-clock-frequency and pixel-clock-frequency have not been
definded as endpoint propierties in the textual bindings, the sensor
does parse them from the endpoint. Thus move these properties to the
endpoint in the new yaml bindings.

-* Aptina 1/2.5-Inch 5Mp CMOS Digital Image Sensor
-
-The Aptina MT9P031 is a 1/2.5-inch CMOS active pixel digital image sensor with
-an active array size of 2592H x 1944V. It is programmable through a simple
-two-wire serial interface.
-
-Required Properties:
-- compatible: value should be either one among the following
-	(a) "aptina,mt9p031" for mt9p031 sensor
-	(b) "aptina,mt9p031m" for mt9p031m sensor
-
-- input-clock-frequency: Input clock frequency.
-
-- pixel-clock-frequency: Pixel clock frequency.
-
-Optional Properties:
-- reset-gpios: Chip reset GPIO
-
-For further reading on port node refer to
-Documentation/devicetree/bindings/media/video-interfaces.txt.
-
-Example:
-
-	i2c0@1c22000 {
-		...
-		...
-		mt9p031@5d {
-			compatible = "aptina,mt9p031";
-			reg = <0x5d>;
-			reset-gpios = <&gpio3 30 0>;
-
-			port {
-				mt9p031_1: endpoint {
-					input-clock-frequency = <6000000>;
-					pixel-clock-frequency = <96000000>;
-				};
-			};
-		};
