Unexpected GPU hang was observed during runpm stress test
on 0x7341 rev 0x00. Further debugging shows broken ATS is
related. Thus as a followup of commit 5e89cd303e3a ("PCI:
Mark AMD Navi14 GPU rev 0xc5 ATS as broken"), we disable
the ATS for the specific SKU also.
V2: cosmetic fix for description part(suggested by Krzysztof)
