commit e5de91e68c5ccaf4ef3e5aa265b469e186ebfa65 (HEAD -> drm-intel-next-queued, drm-intel/drm-intel-next-queued)

    Revert "drm/i915/tgl: Implement Wa_1406941453"
    
    Our sanitychecks indicate that while this register is context
    saved/restore, the HW does not preserve this bit within the register --
    it likely doesn't exist, or one of those mythical bits that the
    architects insist does something despite all appearances to the
    contrary.
    
    For reference, SAMPLER_MODE is already in i915_reg.h as
    GEN10_SAMPLER_MODE and is being setup in icl_ctx_workarounds_init() as
    opposed to the chosen location here of rcs_engine_wa_init).
