We update the timestamping constants per-crtc explicitly in
intel_crtc_update_active_timings(). Furtermore the helper will
use uapi.adjusted_mode whereas we want hw.adjusted_mode. Thus
let's drop the helper call an rely on what we already have in
intel_crtc_update_active_timings(). We can now also drop the
hw.adjusted_mode -> uapi.adjusted_mode copy hack that was added
to keep the helper from deriving the timestamping constants from
the wrong thing.

Does this fix some CI fail? I'd kinda expect/hope for that ...

Anyway looks like a good idea to not mess with the uapi state like this.

Nah. Just trying to get rid of some of the confusing stuff before
we add even more confusing stuff for bigjoiner.
