Align DOCKER_PREFIX with PRIVATE_CONTAINER_REGISTRY

PRIVATE_CONTAINER_REGISTRY is a system wide variable
set in jenkins. This is already used by tf-a jobs.
Rather than creating another variable align this in
job config. Renaming DOCKER_PREFIX to PRIVATE_CONTAINER_REGISTRY
will require additional work as it is used in Docker
image and may break developer workflow.
