* Older firmware have a timing issue with DM that crashes few TF-A

* to detect what current DM version we are running - we rely on the
* corresponding TIFS versioning to handle this check and ensure that
* the platform boots up
*
* Upgrading to TIFS version 9.1.7 along with the corresponding DM from
