[PATCH] drm/amdgpu/ttm: make some functions static

[Russell, Kent]

How would we handle that? Having a revert on amd-kfd-staging? We can ensure that amd-staging-dkms doesn't cherrypick it in, but since KFD merges, it would be more complicated.

We'll need to be careful not to merge this change on amd-kfd-staging and
amd-staging-dkms. On those branches, this function is called from
amdgpu_amdkfd_gpuvm.c.
