Hello Fred Reitberger, Jason Glenesk, Matt DeVillier, Raul Rangel,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/76117?usp=email

to look at the new patch set (#2).

Change subject: soc/amd/common/block/acpi/ivrs: fix missing IOAPIC[1] error

soc/amd/common/block/acpi/ivrs: fix missing IOAPIC[1] error

When probing the resource with the IOMMU_IOAPIC_IDX index, we need to
use the PCI device 0 function 0 on the first bus in the domain for
probing and not the domain device, since the resource isn't on the
domain device, but on the northbridge device which is B0F0D0 in the case
of the APUs.

TEST=This fixes the following error on Mandolin with Picasso:

AMD-Vi: [Firmware Bug]: : IOAPIC[1] not in IVRS table
AMD-Vi: Disabling interrupt remapping
