PCI: Mark AMD Navi14 GPU ATS as broken
commit e8946a53e2a698c148b3b3ed732f43c7747fbeb6 upstream
Observed unexpected GPU hang during runpm stress test on 0x7341 rev 0x00.
Further debugging shows broken ATS is related.
Disable ATS on this part. Similar issues on other devices:
a2da5d8cc0b0 ("PCI: Mark AMD Raven iGPU ATS as broken in some platforms")
45beb31d3afb ("PCI: Mark AMD Navi10 GPU rev 0x00 ATS as broken")
5e89cd303e3a ("PCI: Mark AMD Navi14 GPU rev 0xc5 ATS as broken")
