Convert amdgpu to use ttm_bo_vmap() instead of ttm_bo_kmap(). The latter is deprecated. Passing ttm_bo_vmap()'s locking validation requires to remove the implicit unmap from the BO release path. Smoke-tested with an Radeon RX 460. There's similar patchset for xe at [1], which requires additional changes.
