drm/xe: Set PTE_AE for smem allocations in integrated devices
Without this if a atomic operation is executed in Xe2 integrated GPUs it causes engine memory catastrophic error. This fixes at least 3 failures in piglit sanity and 2 failures in crucible for LNL. v3: - only add PTE_AE to smem in integrated Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
