This deletes the integrator split_by_variant.sh script and defines a number of unique board types for the core modules that are meaningful to support for the Integrator AP/CP, i.e. the ones that did not just say "unsupported core module" in split_by_variant.sh. If more core modules need to be supported they are easy to add. We delete all the old cruft in Makefile and MAKEALL that was working around the old way of building boards. We create a unique config file per board to satisfy the build system, but they are just oneliners that include the existing integratorap.h and integratorcp.h configs.
