PCI: Mark all AMD Navi10 and Navi14 GPU ATS as broken

[ Upstream commit 3f1271b54edcc692da5a3663f2aa2a64781f9bc3 ]

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:
