[PATCH 2/8] dt-bindings: media: ov5645: Convert to json-schema

[Jacopo Mondi <jacopo+renesas@jmondi.org>]

Convert the ov5645 bindings document to json-schema and update
the MAINTAINERS file accordingly, as the entry was not documented.

Add myself as maintainer for odd fixes only, as I don't have the
sensor to test with.

Hello Todor, Manivannan
   I've added in this patch an entry for ov5645 in the MAINTAINERS
file, and I've added myself as maintainers for Odd Fixes only.

As you seem to be the author and committers of this bindings respectively,
would you be interested in maintaining this driver ?

-* Omnivision 1/4-Inch 5Mp CMOS Digital Image Sensor
-
-The Omnivision OV5645 is a 1/4-Inch CMOS active pixel digital image sensor with
-an active array size of 2592H x 1944V. It is programmable through a serial I2C
-interface.
-
-Required Properties:
-- compatible: Value should be "ovti,ov5645".
-- clocks: Reference to the xclk clock.
-- clock-names: Should be "xclk".
-- clock-frequency: Frequency of the xclk clock.
-- enable-gpios: Chip enable GPIO. Polarity is GPIO_ACTIVE_HIGH. This corresponds
-  to the hardware pin PWDNB which is physically active low.
-- reset-gpios: Chip reset GPIO. Polarity is GPIO_ACTIVE_LOW. This corresponds to
-  the hardware pin RESETB.
-- vdddo-supply: Chip digital IO regulator.
-- vdda-supply: Chip analog regulator.
-- vddd-supply: Chip digital core regulator.

-The device node must contain one 'port' child node for its digital output
