[Intel-xe] [PATCH v3 13/14] drm/xe: Add missing LRC workarounds for graphics 1200

[Lucas De Marchi]

Synchronize LRC workarounds for graphics version 1200 with i915 up to
commit 7cdae9e9ee5e ("drm/i915: Move DG2 tuning to the right function").
These were probably missed for TGL/RKL before because in i915 it uses a
!IS_DG1() condition.  Avoid a similar issue by just checking the
graphics version 1200 since DG1 is 1210.
