drm/amdkfd: set uuid for each partition in topology 



Currently each kfd compute partition/node is sharing
the same uuid of AID, which doen't meet the CUDA spec
for visible device, so corresponding XCD id for each
partition in smu has been assigned to xcp, and exposed
to kfd topology.

v2: add NULL check (Lijo)
