Convert the i.MX I2C binding to DT schema format using json-schema,
some improvements applied, such as update example based on latest DT
file, add more compatible for existing SoCs, and remove unnecessary
common property "pinctrl".
Signed-off-by: Anson Huang <[email protected]>

Changes since V1:
- add "additionalProperties: false".

-* Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX
-
-Required properties:
-- compatible :
- - "fsl,imx1-i2c" for I2C compatible with the one integrated on i.MX1 SoC
- - "fsl,imx21-i2c" for I2C compatible with the one integrated on i.MX21 SoC
- - "fsl,vf610-i2c" for I2C compatible with the one integrated on Vybrid vf610 SoC
-- reg : Should contain I2C/HS-I2C registers location and length
-- interrupts : Should contain I2C/HS-I2C interrupt
-- clocks : Should contain the I2C/HS-I2C clock specifier
-
-Optional properties:
-- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
- The absence of the property indicates the default frequency 100 kHz.
-- dmas: A list of two dma specifiers, one for each entry in dma-names.
-- dma-names: should contain "tx" and "rx".
-- scl-gpios: specify the gpio related to SCL pin
-- sda-gpios: specify the gpio related to SDA pin
-- pinctrl: add extra pinctrl to configure i2c pins to gpio function for i2c
- bus recovery, call it "gpio" state

The bus default is up to 3MHz. Is that valid here?

Will remove the type and just use enum for it, it ONLY supports 100KHz/400KHz.

No, it should be either 100KHz or 400KHz, so far on i.MX I2C, ONLY 100KHz/400KHz are
supported/tested.

Will remove -gpios' type/description as it is already defined in i2c-gpio.yaml.
