mb/google/zork: Unmap FCH IO-APIC PCI interrupts
Now that the _PRT generates a GNB IO-APIC routing table we no longer
need to route the PCI interrupts through the FCH IO-APIC. This change
unmaps the IRQs since they are no longer used.
BUG=b:170595019
TEST=Boot with `pci=nomsi amd_iommu=off` and verify /proc/interrupts
