struct nvgpu_gr is right now initialized during probe and from OS specific code. To support multiple instances of graphics engine, nvgpu needs to initialize nvgpu_gr after number of engine instances have been enumerated in poweron path. Hence move nvgpu_gr_alloc() to poweron path and after gr manager has been initialized. Some of the members of nvgpu_gr are initialized in probe path and they too are in OS specific code. Move them to common code in nvgpu_gr_alloc() Add field fecs_feature_override_ecc_val to struct gk20a to store the override flag read from device tree. This flag is later copied to nvgpu_gr in poweron path. Update tpc_pg_mask_store() to check for g->gr being NULL before accessing golden image pointer. Update tpc_fs_mask_store() to return error if g->gr is not initialized. This path needs nvgpu_gr struct initialized. Also fix the incorrect NULL pointer check in tpc_fs_mask_store() which breaks the write path to this sysfs.
