Let's gradually start calling i915 and xe parent, or core, drivers from
display via function pointers passed at display probe.
Going forward, the struct intel_display_parent_interface is expected to
include const pointers to sub-structs by functionality, for example:
struct intel_display_rpm {
struct ref_tracker *(*get)(struct drm_device *drm);
/* ... */
};
struct intel_display_parent_interface {
/* ... */
const struct intel_display_rpm *rpm;
};
This is a baby step towards not building display as part of both i915
and xe drivers, but rather making it an independent driver interfacing
with the two.
v3: useless include additions dropped
v2: unrelated include removal dropped

We haven't updated the DRIVER_TIMESTAMP since commit 3570bd989a
("drm/i915: Update DRIVER_DATE to 20230929") 1½ years ago. Before then,
the previous update was commit 139caf7ca2 ("drm/i915: Update
DRIVER_DATE to 20201103") 4+ years ago. The DRIVER_DATE has also been
removed altogether.
We've used the DRIVER_TIMESTAMP to log suggestions to file bugs on GPU
hangs when they happen on a driver less than six months old. Combined
with the sporadic DRIVER_TIMESTAMP updates, we really haven't logged the
suggestions for years.
Just stop logging the suggestion to file bugs altogether, and remove
DRIVER_TIMESTAMP. This doesn't really change anything wrt to logging GPU
errors or how we handle bugs. And effectively we already stopped logging
the message a year ago when we stopped updating DRIVER_TIMESTAMP.
Instead, add an unconditional message about the GPU error state
location.
