drm/i915: add accounting for mappable objects in gtt v2

Browse source

More precisely: For those that _need_ to be mappable. Also add two
BUG_ONs in fault and pin to check the consistency of the mappable
flag.

Changes in v2:
- Add tracking of gtt mappable space (to notice mappable/unmappable
  balancing issues).
- Improve the mappable working set tracking by tracking fault and pin
  separately.
