[PATCH v2 1/2] dt-bindings: media: i2c: Add OmniVision OV13858

[George Neacsu via B4 Relay]

From: George Neacsu <geocausa@xxxxxxxxx>

The OV13858 is a 13 megapixel sensor with a four-lane MIPI CSI-2 D-PHY
output. So far its driver has only been probed through ACPI. The
Microsoft Surface Pro 11 with a Snapdragon X Elite uses it as the rear
camera and describes it in the device tree.

Describe the sensor input clock, three supplies, reset GPIO and
four-lane CSI-2 endpoint.
