sb/intel/i82801ix: Use the common ACPI pirq generator
For this to work the northbridge and lpc bridge device need acpi_name functions. TESTED on Thinkpad X200, a valid PIRQ routing in SSDT in /sys/firmware/acpi/tables/SSDT Change-Id: I62e520f53fa3f928a8e6f3b3cf33af2acdd53ed9 Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/22980 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
