    southbridge/intel/bd82x6x/acpi: Fix IRQ warnings
    
    The PCIe slot uses Message Signaled Interrupts (MSI) as the
    IGD does and doesn't use hardware INT lines.
    Adding the IRQ entry for PEG slot fixes a warning showing up in
    GNU/Linux dmesg.
    
    Test system:
     * Intel IvyBridge
     * Gigabyte GA-B75M-D3H
