[PATCH 6.12.y] drm/amd/pm: populate unique ID for smu 13.0.7

[Sasha Levin <sashal@kernel.org>]

From: Kevin Wang <kevin.wang@amd.com>

[ Upstream commit 079f9103d9cde68fb2ccc414e94520f43ee102de ]

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")

[ sashal: Moved smu_v13_0_7_get_unique_id() immediately before smu_v13_0_7_ppt_funcs because the upstream neighboring functions are absent. ]
