Subject: [PATCH] Import lc15-sysdev-remap from meta-nrw-bsp

Note: the script is imported as-is, but .bb file is modified because we
use .service file from previous patch instead of init file. I'm not
familiar enough with bitbake to be sure that the changes are correct so
I'd appreciate thorough review.
