soc/amd/root_complex: report IOAPIC resource in !hob case

When no HOB list is found, not only adding the resources reported by the
FSP were skipped, but also adding the GNB IOAPIC resource was skipped.
Fix this bug by moving the reporting of the GNB IOAPIC resource before
the resources reported in the FSP HOBs to not skip the IOAPIC resource
when there's no HOB list.
