[PATCH 7/8] dt-bindings: media: i2c: Add ON Semiconductor LC898123F40

[Gaurav Suman via B4 Relay]

From: Gaurav Suman <gauravsuman007@xxxxxxxxx>

Add bindings for the LC898123F40 optical image stabilisation and
autofocus controller, used in the main camera module of the LG G8x
ThinQ.

This was written and tested with the help of an AI coding assistant
(Claude Opus 5.5, Anthropic); I reviewed the change and the results.

+description:
+  The LC898123F40 is an optical image stabilisation and autofocus
+  controller with built-in flash memory for its firmware, controlled over
+  I2C. It drives the voice coil motors of a camera module. Only the
+  autofocus (lens position) function is described here.
