cover Add LLCC support for SC7180

LLCC behaviour is controlled by the configuration data set in the llcc-qcom driver, add the same for SC7180 SoC. Also add the compatible for SC7180.

The patch is based on linux-next where llcc driver has been made generic and not sdm845 specific.

Can you convert this binding to YAML? Would be useful to make sure it's used properly.
