sb/intel/i82801{g,j}x: Automatically generate ACPI PIRQ tables

Both southbridges need to be done at once since this southbridge code
is used for different northbridges, which fails to compile when done
separately.

This needs an acpi_name functions in the northbridge code to be
defined.

TESTED on Intel DG43GT: show correct PIRQ ACPI entries in
/sys/firmware/acpi/tables/SSDT.
