shutdown_fsm: Add power_ramp_force() to jump straight to the tgt power

Both power_ramp_start() and power_ramp_force() are now small macros
around _power_ramp_start()

The new behavior is:
* ramp down power when stopping bts through Ctrl-C
* the other shutdown causes skip power ramping

This will cause the bts to reconnect faster when the oml link is
dropped and power ramping is enabled.
