/*
 * Document #640228 Meteor Lake - U/H and U Type4 Processor - 2.3 Device IDs - Table 8 "Other
 * Device ID" specifies that the first Thunderbolt PCIe root port number is 16. TBT's LCAP
 * registers return port index which starts from 16 (usually for other PCIe root ports index
 * starts from 1). Thus, keeping lcap_port_base 16 for TBT, so that coreboot's PCIe remapping
 * logic can return a correct index (0-based).
