[ Upstream commit dd886a63d6e2ce5c16e662c07547c067ad7d91f5 ]
GGTT mappings reside on the device and this state is lost during suspend / d3cold thus this state must be restored resume regardless if the BO is in system memory or VRAM.
v2: - Unnecessary parentheses around bo->placements[0] (Checkpatch)
