dt-bindings: i2c: Convert i2c-jz4780.txt to YAML

Convert the i2c-jz4780.txt file to ingenic,i2c.yaml.

Two things were changed in the process:
- the clock-frequency property can now only be set to the two values
  that can be set by the hardware;
- the dmas and dma-names properties are now required.

-* Ingenic JZ4780 I2C Bus controller
-
-Required properties:
-- compatible: should be one of the following:
-  - "ingenic,jz4780-i2c" for the JZ4780
-  - "ingenic,x1000-i2c" for the X1000
-- reg: Should contain the address & size of the I2C controller registers.
-- interrupts: Should specify the interrupt provided by parent.
-- clocks: Should contain a single clock specifier for the JZ4780 I2C clock.
-- clock-frequency: desired I2C bus clock frequency in Hz.
-
-Recommended properties:
-- pinctrl-names: should be "default";
-- pinctrl-0: phandle to pinctrl function
-
