[PATCH 1/8] drm/i915/display: update intel_enabled_dbuf_slices_mask to use intel_display

[Vinod Govindapillai]

Update intel_enabled_dbuf_slices_mask to use intel_display instead
of drm_i915_private object. This is a prepratory patch for the next
patch in the series, where all intel_de_read calls in skl_watermarks.c
are updated to use intel_display instead of drm_i915_private.
