soc/intel/dnv: Fix ACPI reporting of root port interrupt routing
pcie_port.asl defines an IRQM method that looks up legacy interrupt
swizzling based on incoming interrupt "pin" A-D and root port number.
Unfortunately the 8-bit root port number stored at offset 0x4F in the
config space matches the device number, not the 1-8 scheme used in
the LUT reported to the OS.
Fix the case values to match the hardware.
