drm/xe: Restore system memory GGTT mappings
[ 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) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241031182257.2949579-1-matthew.brost@intel.com (cherry picked from commit a19d1db9a3fa89fabd7c83544b84f393ee9b851f) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Stable-dep-of: 46f1f4b0f3c2 ("drm/xe: improve hibernation on igpu") Signed-off-by: Sasha Levin <sashal@kernel.org>
