Track every intel_gt_pm_get() until its corresponding release in
intel_gt_pm_put() by returning a cookie to the caller for acquire that
must be passed by on rleased. When there is an imbalance, we can see who
either tried to free a stale wakeref, or who forgot to free theirs.
Beside reusing existing code, the main advantage of ref_tracker is
tracking per instance of wakeref. It allows also to catch double
put.
On the other side we lose information about the first acquire and
the last release, but the advantages outweigh it.

Hi Matthias,
could you open a ticket at gitlab, providing a dmesg as described at
https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs
Thanks,
Imre

If there is a tool somewhere that displays this info, that would be

Move intel_crtc_pch_transcoder() and has_pch_trancoder() to a
more appropritate place (intel_pch_display.c).

Move the ibx pch port sanitation code into intel_pch_display.c
where it now belongs.

Now that we track framestart_delay in the crtc state with readout
and state checker support we can remove the explicit framestart_delay
sanitation code.
Also I'm not convinced reprogramming this while the pipe is running
is even valid. CHICKEN_TRANS (hsw+) and TRANS_CHICKEN2
From: Ville Syrjälä
We need to make framestart_delay dynamic for DRRS on PCH
ports. To that end move it into the crtc state. As a bonus
we get state check+dump for it. Will also allow us to get
rid of the somewhat questionable framestart_delay sanitation
code.
