soc/amd/*/root_complex: introduce get_iohc_fabric_id
Implement get_iohc_fabric_id for each SoC that translates the coreboot domain number to the fabric ID of the corresponding PCI root. This allows the primary domain to have the number 0 even though the destination data fabric ID will be non-zero. Keeping the primary domain number 0 allows to use config_of_soc() which can be resolved at link time and not need to dynamically find the SoC device to get the config.
