There are enough vbios escapes without the proper workaround
that some users still hit this.  MS never productized ATS on
windows so OEM platforms that were windows only didn't always
validate ATS.

The advantages of ATS are not worth it compared to the potential
instabilities on harvested boards.  Just disable ATS on all navi10
and 14 boards.

Thanks, applied to for-linus for v5.17 with commit log:

    PCI: Mark all AMD Navi10 and Navi14 GPU ATS as broken
    
    There are enough VBIOS escapes without the proper workaround that some
    users still hit this.  Microsoft never productized ATS on Windows so OEM
    platforms that were Windows-only didn't always validate ATS.
    
    The advantages of ATS are not worth it compared to the potential
    instabilities on harvested boards.  Disable ATS on all Navi10 and Navi14
    boards.
    
    Symptoms include:
