Subject: rename DEVICE to ADK_TARGET

- the name is better, because qemu f.e. is no hardware device
- use make TARGET=alix1c to start with a configuration for this target
- use make TARGET=alix1c allmodconfig to generate a mostly complete config
  to build all available packages for this platform as a package

The all.config and .defconfig files needed to get this working are
dynamically generated.
