Adrian Freihofer c2813a4c69 devtool: refactor deploy-target
Make the deploy function independent from d. This allows to call the
function also from Python code not running in bitbake.
This is needed to for the devtool ide plugin which will call the
do_install task and the code from devtool deploy-target independently
from a bitbake server. This allows a much quicker workflow.
