This table was wrong. It's also produced by the SoC code now.

/*
* This table doesn't actually perform any routing. It only populates the
* PCI_INTERRUPT_LINE register on the PCI device with the PIC value specified
* in fch_apic_routing. The linux kernel only looks at this field as a backup
* if ACPI routing fails to describe the PCI routing correctly. The linux kernel
* also uses the APIC by default, so the value coded into the registers will be
* wrong.
*
* This table is also confusing because PCI Interrupt routing happens at the
* device/slot level, not the function level.
