[PATCH 5/6] drm/i915/power: Convert "i830 power well" code to intel_display

Fri Sep 6 14:33:05 UTC 2024
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
struct intel_display will replace struct drm_i915_private as
the main thing for display code. Convert the "i830 power well"
code to use it (as much as possible at this stage).
