drm/ttm: move the LRU into resource handling v4
This way we finally fix the problem that new resource are
not immediately evict-able after allocation.
That has caused numerous problems including OOM on GDS handling
and not being able to use TTM as general resource manager.
v2: stop assuming in ttm_resource_fini that res->bo is still valid.
v3: cleanup kerneldoc, add more lockdep annotation
v4: consistently use res->num_pages
