drm/i915/ttm: add unmap_virtual callback
Ensure we call ttm_bo_unmap_virtual when releasing the pages.
Importantly this should now handle the ttm swapping case, and all other
places that already call into i915_ttm_move_notify().
v2: fix up the selftest
Fixes: cf3e3e86d779 ("drm/i915: Use ttm mmap handling for ttm bo's.")
