BUILD: Makefile: add options to build with DeviceAtlas

This diff updates the Makefile to compile conditionally via
some new sets of flags, USE_DEVICEATLAS to enable the module
and the couple DEVICEATLAS_INC/DEVICEATLAS_LIB which needs to
point to the API root folder in order to compile the API and
the module.
