We get 7 warnings when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:1990:5: warning: no previous prototype for 'amdgpu_pre_soft_reset' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c:1548:5: warning: no previous prototype for 'amdgpu_connector_virtual_dpms' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c:1560:5: warning: no previous prototype for 'amdgpu_connector_virtual_set_property' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c:330:5: warning: no previous prototype for 'amdgpu_cs_list_validate' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/dce_virtual.c:98:6: warning: no previous prototype for 'dce_virtual_stop_mc_access' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/dce_virtual.c:130:6: warning: no previous prototype for 'dce_virtual_resume_mc_access' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/dce_virtual.c:136:6: warning: no previous prototype for 'dce_virtual_set_vga_render_state' [-Wmissing-prototypes]
In fact, all of the functions are only used in the file
in which they are declared and don't need a declaration,
but can be made static.
So this patch marks both functions with 'static'.

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/si.c:908:5: warning: no previous prototype for 'si_pciep_rreg' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/si.c:921:6: warning: no previous prototype for 'si_pciep_wreg' [-Wmissing-prototypes]
In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.
