drm/i915: Do not make assumptions on GGTT VMA sizes
GGTT VMA sizes might be smaller than the whole object size due to
different GGTT views.
v2:
- Separate GGTT view constraint calculations from normal view
constraint calculations (Chris Wilson)
v3:
- Do not bother with debug wording. (Tvrtko Ursulin)
v4:
- Clearer logic for calculating map_and_fenceable (Tvrtko Ursulin)
