depends on the following change
https://lore.kernel.org/all/20221003125141.123759-1-jonathanh@nvidia.com/
V2 -> V3:nothing has changed but added the dependency here
V1 -> V2:removed the redundant cells and status in ucsi-ccg.
Using dash instead of underscore in the ucsi-ccg node name.
Using representive name in cypress,firmware-build property.
