Allocates 1 TB of memory. Test is disabled by default
since it's triggers OOM killer.
v2:
FIx the test to only alloc the BO and assert if return value
not equal to -ENOMEM and remove test disable on start.

I was just about to scream that you need to fix the helper first, but
then I saw that you now directly use amdgpu_bo_alloc().
The commit message could be changed and for the unlikely case that we
actually can allocate a BO of 1TB size we should free it.
But apart from that the patch looks good to me and is Acked-by:
Christian König <christian.koenig@xxxxxxx>.

Christian.
