drm/amd/powerplay: fix VoltageObjectInfo zero-stride loop and OOB read
Reject voltage objects whose usSize is smaller than the header or would
advance the cursor past the table end, preventing an infinite loop or
heap OOB read when the VBIOS supplies a malformed VoltageObjectInfo table.
Fixes: c82baa281843 ("drm/amd/powerplay: add Tonga dpm support (v3)")
Fixes: 0d2c7569e196 ("drm/amdgpu: add new atomfirmware based helpers for powerplay")
