gpu: drm: amd: amdgpu: amdgpu: Mark global variables as __maybe_unused
These 3 variables are used in *some* sourcefiles which include
amdgpu.h, but not *all*. This leads to a flurry of build warnings.
Fixes the following W=1 kernel build warning(s):
from drivers/gpu/drm/amd/amdgpu/amdgpu.h:67,
drivers/gpu/drm/amd/amdgpu/amdgpu.h:198:19: warning: ‘no_system_mem_limit’ defined but not used [-Wunused-const-variable=]
drivers/gpu/drm/amd/amdgpu/amdgpu.h:197:19: warning: ‘debug_evictions’ defined but not used [-Wunused-const-variable=]
drivers/gpu/drm/amd/amdgpu/amdgpu.h:196:18: warning: ‘sched_policy’ defined but not used [-Wunused-const-variable=]
NB: Repeats ~650 times - snipped for brevity.
