msm: mdss: Clean up PP framework for unchanged PP features

When creating the framework for handling PP versioning, all PP features
were given interface update and space in the framework for handling
versioning. However, the CSC hardware will not change, and
therefore will not need any updates. This change removes the framework
update done for CSC.
