Qualcomm SM8650 SoC has three CCI controllers with two I2C busses
connected to each of them.
The CCI controllers on SM8650 are compatible with the ones found on
many other older generations of Qualcomm SoCs.

The DT should never ever touch the _SRC clocks directly, especially since

Please stick to a single naming scheme (cciX_Y or csiN)
