916f2740b8 drm/i915/reset: add modeset_stuck callback to intel_display_reset_prepare()
Drop the dependency on gt by providing a callback for trying to unbreak
stuck modeset. Do intel_gt_set_wedged() via the callback.

It's by no means pretty, but this is perhaps the most straightforward
alternative.

Deduplicate the gpu_reset_clobbers_display() part by passing the
information in from gt side.

ea349ec038 drm/i915/reset: remove I915_RESET_MODESET flag
Since commit d59cf7bb73 ("drm/i915/display: Use dma_fence interfaces
instead of i915_sw_fence") we don't have anyone waiting on the
I915_RESET_MODESET bit, and there's no need for its semantics. Instead,
simply return true from intel_display_reset_prepare() to indicate that
intel_display_reset_finish() should be called.

fddbcd1532 drm/i915/reset: add intel_display_reset_test()
Add a helper for checking if we want to test display reset regardless of
whether it's strictly necessary. This will come in handy in follow-up
work where we want to check this from gt reset side.

v2: Drop superfluous newline

6498a5e010 drm/i915/display: convert display reset to struct intel_display *
Going forward, struct intel_display will be the main display device
structure. Convert display reset to it as much as possible.

59c6106e27 drm/i915/display: add intel_display_reset.[ch]
Split out the display reset functionality to a separate file to
declutter intel_display.c. Rename the functions accordingly. The minor
downside is having to expose __intel_display_resume().
