soc/intel/alderlake: Add IRQ mapping for PEG PCI-E ports

ACPI _PRT method was missing from PEG (SoC PCI-E) links, resulting in
OS complaining about interrupt routing:
    pcieport 0000:00:06.0: can't derive routing for PCI INT A

Tested on `starbook_adl` with Ubuntu 24.04 by running SSD
benchmark with GNOME disks and suspend.
