at: wake only when sending AT commands

Browse Source 
Allow the modem to enter soft sleep when
we don't talk to the modem using AT commands.
This was already the case in suspend, but
not during runtime. By only waking the modem
from soft sleep when we need to send
an AT command, we can save some power.
