[Yang Yingliang]

Fix the compile warning:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_hwseq.c:322:27: warning: variable ‘optc’ set but not used [-Wunused-but-set-variable]
  struct timing_generator *optc;
                           ^~~~
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_hwseq.c:641:7: warning: variable ‘is_dp’ set but not used [-Wunused-but-set-variable]
  bool is_dp;
       ^~~~~
