drm/amdkfd: Reconcile the definition and use of oem_id in struct kfd_topology_device
Currently oem_id is defined as uint8_t[6] and casted to uint64_t*
in some use case. This would lead code scanner to complain about
access beyond. Re-define it in union to enforce 8-byte size and
alignment to avoid potential issue.
