drm/xe: Move LRC_ENGINE_ID_PPHWSP_OFFSET outside of parallel offset
The parallel scratch layout spans 2k and LRC_ENGINE_ID_PPHWSP_OFFSET
lands within than space. This happens to be ok as the offset lands in
reserved part of guc_sched_wq_desc, but for future safety move
LRC_ENGINE_ID_PPHWSP_OFFSET to the unused offset of 1024 below parallel
scratch layout.
