Introduce bts_shutdown FSM

Using an FSM here will allow for more complex ordered shutdown
procedures, like power ramp down, waiting for TRX deact asyncrhonously,
etc.

Current commit leaves everything in place already prepared to implement
ramp down, which will be implemented in next commit in the series.
