[PATCH 1/5] dt-bindings: media: i2c: Add Sony IMX355

[Richard Acayan <mailingradian@gmail.com>]

The IMX355 camera sensor is a camera sensor that can be found as the
front camera in some smartphones, such as the Pixel 3, Pixel 3 XL, Pixel
3a, and Pixel 3a XL. It already has a driver, but needs support for
device tree. Document the IMX355 to support defining it in device tree.
