sb/intel/common: Automatically generate ACPI PIRQ
Based on change I2b5d68adabf0840162c6f295af8d10d8d3007a34
(sb/intel/common: Add function to automatically generate ACPI PIRQ).
This adds functionality to generate PIRQ ACPI tables automatically based
on the chipset registers.
Mapping of PCI interrupt pin to PIRQ is done by the chipset-specific
intel_common_map_pirq() function, an shared implementation of which is
provided for the bd82x6x, i82801, i89xx, ibexpeak and lynxpoint
chipsets.
