[Skiboot] [PATCH V3 08/15] core/pldm: Update or create terminus locator in the given repo

Tue Sep 13 20:27:17 AEST 2022
The Terminus Locator PDR forms the association between a TID and PLDM
Terminus Handle for a terminus.
This patch allows to add terminus locator record in the repository.
If a record matches with the Host TID, we activate the current terminus
locator record, otherwise a new record is created.
