drm/i915/vrr: Generate VRR "safe window" for DSB
Looks like TRANS_CHICKEN bit 31 means something totally different
depending on the platform:
TGL: generate VRR "safe window" for DSB
ADL/DG2: make TRANS_SET_CONTEXT_LATENCY effective with VRR
So far we've only set this on ADL/DG2, but when using DSB+VRR
we also need to set it on TGL.
And a quick test on MTL says it doesn't need this bit for either
of those purposes, even though it's still documented as valid
in bspec.
