Subject: [PATCH] wavecom: implement power off

Powering off Wavecom devices is done via the AT^CPOF=1 command. These devices
seem to not only power-off, but also power-cycle when this command is received,
which means that the user needs to make sure to fully cut the power to the
device when the SetPowerState() method replies.
