soc/amd/common/block/pci: Implement acpigen_write_pci_{GNB,FCH}_PRT

This is loosely based off of picasso/pcie_gpp.c. This version uses the
acpigen_write_PRT_X methods to write the actual records. There are also
two functions, 1 for using the GNB, and one for using the FCH. The FCH
one is useful when the GNB IO-APIC has not been initialized.

TEST=Dump guybrush ACPI and verify it looks correct
