[PATCH v3 2/3] deploy boot files via sstate-cache

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch changes how we deploy the boot files.
Instead of manually deploying, we use the sstate infrastructure for
that. By that, accidental overrides of the artifacts can be
automatically detected. On clean, the artifacts are also cleaned.
