nb/intel/snb: Add PCI routing table for PEG root ports
Previously the PRTs were defined in southbridge code (8014714
southbridge/intel/bd82x6x/acpi: Fix IRQ warnings), but this was lost
when southbridge PRTs became autogenerated. Add the proper PRTs for the
PCI express for graphics root ports.
This (again) fixes warnings issued by Linux for interrupts on secondary
functions of devices on the PEG ports, such as the HDMI audio controller
on graphics cards.
pcieport 0000:00:01.0: can't derive routing for PCI INT B
snd_hda_intel 0000:01:00.1: PCI INT B: no GSI
Tested with GIGABYTE P67A-UD3R (CB:31363) with Radeon HD 5670.
