drm/amdgpu: Add ualink handle to BOs

Browse source

Add a ualink handle to the amdgpu_bo struct. The ualink
handle is a 128-bit unique identifier associated with a
BO and is shared across the network to facilitate NPA based
memory sharing across GPUs in a rack scale setup.
We are only storing the low 64 bits of that handle in the BO
struct as that is gauranteed to be unique.
