soc/amd/common/acpi/ivrs: probe IOAPIC device on domain device 

This reverts commit e33d253793 ("soc/amd/common/block/acpi/ivrs: fix
missing IOAPIC[1] error").

Now that the per PCI root domain IOAPIC MMIO resource is reported on the
domain device, we can again probe the resource on the domain device
instead of the northbridge PCI device in that domain. This will make the
IVRS code compatible again with the work in progress Genoa SoC support.

TEST=Linux doesn't complain about the IOAPIC[1] missing in the IVRS on
Mandolin.
