[PATCH 1/2] dt-bindings: media: i2c: Add OmniVision OG0VA1B

[Wenmeng Liu]

Add devicetree binding for OmniVision OG0VA1B image sensor.
OmniVision OG0VA1B is an image sensor, which produces frames in 10-bit
raw output format (Y10) over a 1-lane MIPI CSI-2 interface and supports
the 640x480 (VGA) resolution.

+description:
+  The OmniVision OG0VA1B is a 1/10-inch black and white CMOS VGA (640x480)
+  image sensor. It is controlled over an I2C-compatible SCCB bus and transmits
+  images on a 1-lane MIPI CSI-2 output interface.
