Same for ttm_bo_kunmap() and ttm_bo_vunmap(). There's now one less driver depending on the deprecated ttm_bo_kmap(). Also allows for dropping struct ttm_bo_kmap_obj in favor of struct iosys_map, which is the preferred representation of BO memory mappings. Manual type conversion in amdgpu_bo_kptr() is required to make the returned pointer usable within amdgpu. In a follow-up patch, amdgpu should be convert to use struct iosys_map directly.
