drm/i915/psr: Add helper to get min psr guardband
Introduce a helper to compute the max link wake latency when using
Auxless/Aux wake mechanism for PSR/Panel Replay/LOBF features.
This will be used to compute the minimum guardband so that the link wake
latencies are accounted and these features work smoothly for higher
refresh rate panels.
v2:
- Account for flag `req_psr2_sdp_prior_scanline` and scl lines while
computing min guardband. (Jouni)
- Use wake lines only for eDP with panel_replay and sel_update flags
set. (Jouni)
