From: Ville Syrjälä <[email protected]>
Introduce skl_prefill and various accompanying helpers to do
pipe prefill latency related stuff (vblank/guardband length
checks, and in the future reduced guardband length).
Still a bit rough in plaeces but hopefull good enough to
roll out.
v2: Always use worst case cdclk estimate for now
Drop excessive debugs
Fix missing <<16 for framestart_delay
Use Ankit's intel_crtc_vblank_length()
Some spit and polish here and there
