CONFIG_GK20A_CDE has not even been used for enabling CDE, just for initializing it at boot time, and it was disabled; initialization has been done late when the engine is first used. Remove the config setting and add information about CDE support in gk20a platform data, forcing the initialization at boot time. Boot time init removes rare race conditions when CDE would be initialized by first user.
