x86/amd-iommu: Fix boot crash with hidden PCI devices
commit 26018874e3584f1658570d41d57d4c34f6a53aa0 upstream.
Some PCIe cards ship with a PCI-PCIe bridge which is not
visible as a PCI device in Linux. But the device-id of the
bridge is present in the IOMMU tables which causes a boot
crash in the IOMMU driver.
This patch fixes by removing these cards from the IOMMU
handling. This is a pure -stable fix, a real fix to handle
this situation appriatly will follow for the next merge
window.
