Add the Arducam Pivariety V4L2 sensor driver and integrate it with the media I2C Kconfig and Makefile. Add a T3 Gemstone O1 CSI0 Device Tree overlay for the Arducam Pivariety IMX230 camera module and include it in the K3 overlay build. Enable Device Tree symbol generation so the Kbuild output matches the validated runtime overlay. The Pivariety driver implementation is adapted from: https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver Reference upstream repository snapshot: 7d49aa22558254cd415ef5bbca458a39ad130dce The upstream src/arducam.c content was last changed in: 59157aae2f3dc4e6e3b1f312cafd36b43edbc13e The implementation in this change is adapted for the T3 Gemstone O1 Linux 6.12.24-ti kernel tree.

Summary
Add Arducam Pivariety camera support to the T3 Gemstone O1 Linux kernel tree.
This change:
The existing IMX219 driver and overlay are not modified.
Tested hardware
Validated format
The final validated capture configuration is:
SRGGB10_1X10RG101920x1080The companion userspace ISP pipeline uses
rggb10.Validation
Validated on T3 Gemstone O1 hardware:
The Device Tree overlay was rebuilt from the final PR source.
