drm/ttm: add a weak BO reference to the resource v3
Keep track for which BO a resource was allocated.
This is necessary to move the LRU handling into the resources.
A bit problematic is i915 since it tries to use the resource
interface without a BO which is illegal from the conceptional
point of view.
v2: Document that this is a weak reference and add a workaround for i915
v3: further document that this is protected by ttm_device::lru_lock and
clarify the i915 workaround
