drm/ttm: turn ttm_bo_device.vma_manager into a pointer
Rename the embedded struct vma_offset_manager, new name is _vma_manager.
ttm_bo_device.vma_manager changed to a pointer.
The ttm_bo_device_init() function gets an additional vma_manager
argument which allows to initialize ttm with a different vma manager.
When passing NULL the embedded _vma_manager is used.
All callers are updated to pass NULL, so the behavior doesn't change.
