dt-bindings: i2c: Convert i2c-gpio binding to json-schema

Convert the i2c-gpio binding to DT schema format using json-schema. This
serves as an example of how to include other schema (i2c-controller.yaml
in this case).

-Device-Tree bindings for i2c gpio driver
-
-Required properties:
-	- compatible = "i2c-gpio";
-	- sda-gpios: gpio used for the sda signal, this should be flagged as
-	  active high using open drain with (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)
-	  from <dt-bindings/gpio/gpio.h> since the signal is by definition
-	  open drain.
-	- scl-gpios: gpio used for the scl signal, this should be flagged as
-	  active high using open drain with (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)
-	  from <dt-bindings/gpio/gpio.h> since the signal is by definition
-	  open drain.
-
-Optional properties:
-	- i2c-gpio,scl-output-only: scl as output only
-	- i2c-gpio,delay-us: delay between GPIO operations (may depend on each platform)
-	- i2c-gpio,timeout-ms: timeout to get data
-
-Deprecated properties, do not use in new device tree sources:
-	- gpios: sda and scl gpio, alternative for {sda,scl}-gpios
-	- i2c-gpio,sda-open-drain: this means that something outside of our
-	  control has put the GPIO line used for SDA into open drain mode, and
-	  that something is not the GPIO chip. It is essentially an
-	  inconsistency flag.
-	- i2c-gpio,scl-open-drain: this means that something outside of our
-	  control has put the GPIO line used for SCL into open drain mode, and
-	  that something is not the GPIO chip. It is essentially an
-	  inconsistency flag.
-
-Example nodes:
-
-#include <dt-bindings/gpio/gpio.h>
