[layer23 / layer1] Added interface for changing crypto mode of DSP

The layer23 will now set crypto mode and key when CIPHERING MODE COMMAND is
received. After crypto mode has been set, CIPHERING MODE COMPLETE is sent.

NOTE: Layer1 implements only the interface, there is no functionality to it
yet.
