sb/intel/common: Refactor _PRT generation to support GSI-based tables

Newer Intel SoCs also support _PRT tables, but they route PCI devices to
more than just PIRQs, and statically specify IRQs insteade of using link
devices. Extend/refactor intel_acpi_gen_def_acpi_pirq to support this
additional use case.
