soc/amd/picasso: Correctly populate the PCI interrupt line register
The PCI interrupt line registers are used as a last resort if routing
can't be fetched from either ACPI or the MPTable. This change correctly
sets the registers. It overrides the pirq_data set by the mainboards
since the routing is fixed in AGESA.
BUG=b:170595019
TEST=Boot ezkinil with `pci=nomsi,noacpi amd_iommu=off noapic`
Verified all PCI peripherals are still functional.
