Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/amd/amdgpu/si_dpm.c: In function 'si_program_response_times':
drivers/gpu/drm/amd/amdgpu/si_dpm.c:4101:29: warning:
variable 'backbias_response_time' set but not used [-Wunused-but-set-variable]
It's never used since introduction in 841686df9f7d ("drm/amdgpu: add SI DPM
support (v4)"), so can be removed
