e46f468fef drm/ttm: drop special pipeline accel cleanup function. 
The two accel cleanup paths were mostly the same once refactored.

Just pass a bool to say if the evictions are to be pipelined.

3a4ab168a5 drm/ttm: split bound/populated flags. 
Move bound up into the bo object, and keep populated with the tt
object.

The ghost object handling needs to follow the flags at the bo
level now instead of it being part of the ttm tt object.

97588b5b9a drm/ttm: remove pointers to globals

make to much sense having pointers to global structures all around the code.

07583467c2 drm/ttm: remove embedded vma_offset_manager 
No users left.  Drivers either setup vma_offset_manager themself
(vmwgfx) or pass the gem vma_offset_manager to ttm_bo_device_init
(all other drivers).
