drm/amdgpu: Implement UALink handle export

Browse source

This patch adds the implementation for exporting a ualink
handle associated with a BO. If the BO doesn't have a
ualink handle generated yet, we first allocate a unique
ualink handle, add it to a lookup table and return the
handle to user-space.
