Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c: In function 'gfx_v8_0_pre_soft_reset':
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:4950:27: warning:
variable 'srbm_soft_reset' set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c: In function 'gfx_v8_0_post_soft_reset':
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:5054:27: warning:
variable 'srbm_soft_reset' set but not used [-Wunused-but-set-variable]
It never used since introduction in commit d31a501ead7f ("drm/amdgpu: add
pre_soft_reset ip func") and e4ae0fc33631 ("drm/amdgpu: implement
gfx8 post_soft_reset")
