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().

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 Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/487dec72f753302cd565c3a8164afa7fc1e12ed7.1741001054.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>

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.

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.
