Felix Held 416cc66592 soc/amd: commonize PCI root IOAPIC initialization
Make the initialization of the IOAPIC(s) in the PCI root(s) common
across all AMD family 17h+ SoCs. For this the more general
implementation from the Genoa code that supports multiple PC roots is
moved to the common AMD code. All other family 17h+ SoCs are then
adapted to use the common code. For those non-Genoa SoCs, the
initialization of this second IOAPIC is moved from the northbridge
device to the domain device above to match Genoa.

Test=Both the FCH IOAPIC and the PCIe root IOAPIC are still initialized
on Mandolin
