soc/amd/stoneyridge/acpi: use common AMD MADT code

Now that Stoneyridge also reports the GNB IOAPIC on the domain and with
the IOMMU_IOAPIC_IDX resource index the common AMD MADT code expects, we
ca switch over to using this common code on Stoneyridge too.

TEST=The resulting MADT doesn't change on Careena
