New radio transceiver interface

[phuong-nm]

Power-saving modules such as X-MAC or Smart-MAC requires additional functionalities from radio driver. Therefore current radio driver APIs should be expanded or reorganized with minimal changes required.
The proposed radio driver API and related example codes can be found under following directory of branch feature/power_saving
/emb6/target/if/cc1120

Please, remember that we have a separate folder for all DLL related sublayers.

Thanks. I am aware of this fact. Those new modules are temporarily under one directory for sake of simplified testing purpose only. In next commit they are to be placed in right directory.
