drm/ttm: rename bo->mem and make it a pointer

Browse Source 
When we want to decouble resource management from buffer management we need to
be able to handle resources separately.

Add a resource pointer and rename bo->mem so that all code needs to
change to access the pointer instead.

No functional change.
