[RFC PATCH 10/22] drm/i915/display: Remove unused frontbuffer references from intel_overlay

[Jouni Högander]

Overlay is currently calling many frontbuffer tracking interfaces.
We are following new strategy to rely purely on dirtyfb
callback. Remove all other references to frontbuffer tracking code
from intel_overlay.
