- Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709"

  The intent of Wa_14015141709 was to inform us that userspace can no
  longer control object-level preemption as it has on past platforms
  (i.e., by twiddling register bit CS_CHICKEN1[0]).  The description of
  the workaround in the spec wasn't terribly well-written, and when we
  requested clarification from the hardware teams we were told that on the
  kernel side we should also probably stop setting
  FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the
  hardware to honor the settings in per-context register CS_CHICKEN1.  It
  turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a
  mistake; even though CS_CHICKEN1[0] is non-operational and useless to
  userspace, there are other bits in the register that do still work and
  might need to be adjusted by userspace in the future (e.g., to implement
  other workarounds that show up).  If we don't set
  FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would
  not take effect.
