siemens/mc_apl3: Adjust Legacy IRQ routing for PCI devices

On this mainboard there is a legacy PCI device, which is connected to
the PCIe root port via a PCIe-2-PCI bridge. This device only supports
legacy interrupt routing. For this reason we have to adjust the PIR6
register (0x314c) which is responsible for PCIe device 13h and 14h. This
means that the interrupt routing will also be the same for both PCIe
devices. The bridge is connected to PCIe root port 2 and 3 over two
lanes (Device 13.0 and 13.1).

The following routing is required:
INTA#->PIRQD#, INTB#->PIRQA#, INTC#->PIRQB#, INTD#->PIRQC#
