drm/xe: Fix WA 14010918519 write to wrong register

FORCE_SLM_FENCE_SCOPE_TO_TILE and FORCE_UGM_FENCE_SCOPE_TO_TILE are in
the up dword of LSC_CHICKEN_BIT_0 register. Also, the 14010918519
workaround only applies to early steppings, A*. Eventually those should
be dropped, like they were in commit eaeb4b36 ("drm/i915/dg2: Drop
pre-production GT workarounds"), so let's make sure they are annotated
appropriately.
