[PATCH v2 1/3] dt-bindings: media: i2c: Add imx708 image sensor

[Jai Luthra <jai.luthra@ideasonboard.com>]

Sony IMX708 is an 11.9 Megapixel CMOS sensor, that can output pixels
over MIPI CSI-2 bus. Add bindings for it.

+description:
+  The Sony IMX708 is a 1/2.3-inch CMOS active pixel digital image sensor
+  with an active array size of 4608H x 2592V. It is programmable through
+  I2C interface. The I2C address is fixed to 0x1A as per sensor data sheet.
+  Image data is sent through MIPI CSI-2, which is configured as either 2 or
+  4 data lanes.
