[PATCH] drm/amd/pm: populate unique ID for smu 13.0.7

[Kevin Wang]

The smu 13.0.7 backend does not register get_unique_id, leaving
adev->unique_id at zero and KFD topology without the stable GPU
identifier consumed by HIP.

The failure is observed at:
    auto ierr = hipDeviceGetUuid(&uuid, 0);

Fixes: 113cc31dde66 ("drm/amd/pm: add SMU_13_0_7 ppt_funcs for SMU_13_0_7")
