PCI/TSM, the PCI core functionality for the PCIe TEE Device Interface Security Protocol (TDISP), has a need to walk all subordinate functions of a Device Security Manager (DSM) to setup a device security context. A DSM is physical function 0 of multi-function or SR-IOV device endpoint, or it is an upstream switch port. In error scenarios or when a TEE Security Manager (TSM) device is removed it needs to unwind all established DSM contexts. Introduce reverse versions of PCI device iteration helpers to mirror the setup path and ensure that dependent children are handled before parents.
