This allows blocking for BOs to become available
in the memory management.
Amdgpu is doing this for quite a while now during CS. Now
apply the new behavior to all drivers using TTM.

For new submission ib, CE/DE metadata should be programmed to 0;
for partially execution ib, CE/DE metadata should be restored.

This avoids OOM situations when we have lots of threads
submitting at the same time.
v3: apply this to the whole driver, not just CS

We are already doing this for DMA-buf imports and also for
amdgpu VM BOs for quite a while now.
If this doesn't run into any problems we are probably going
to stop removing BOs from the LRU altogether.
v2: drop BUG_ON from ttm_bo_add_to_lru

Let's start to allocate VM PDs/PTs on demand instead of pre-allocating
them during mapping.

drivers/gpu/drm/amd/amdgpu/amdgpu_csa.c:49 amdgpu_allocate_static_csa()
error: uninitialized symbol 'ptr'.
the test if (!bo) doesn't work, as the bo is a pointer to a pointer.
if bo create failed, the *bo will be set to NULL.
so change to test *bo.

In baremetal, also need to reserve csa for preemption.
so move the csa related code out of sriov.
