arm64: dts: qcom: sm8550: add description of CCI controllers

Qualcomm SM8550 SoC contains 3 Camera Control Interface controllers
very similar to the ones found on other Qualcomm SoCs.

One noticeable difference is that cci@ac16000 controller provides only
one I2C bus and has an additional control over AON CCI pins gpio208
and gpio209, but this feature is not yet supported in the CCI driver.
