drm/i915: move modesetting core code under display/
Now that we have a new subdirectory for display code, continue by moving modesetting core code. display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this is, again, a surprisingly clean operation. v2: - don't move intel_sideband.[ch] (Ville) - use tabs for Makefile file lists and sort them Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190613084416.6794-3-jani.nikula@intel.com
