Fixes https://jira.digi.com/browse/DEL-366
Signed-off-by: Alex Gonzalez <alex.gonzalez@digi.com>
This commit separates the BSP layer from the DEL distribution layer. This
allows for customers to use the BSP layer while customizing their own
distribution, and for other Digi teams, like the gateways, to do the same.
It would also allow to use the DEL layer over other BSPs.
