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'.
