cinterion: enable power-off command to go to sleep/standby mode

Browse Source 
AT+CFUN=4 will be used when available to go to standby mode. If not supported,
(as in EGS5) AT+CFUN=7 will be used instead, which enables a CYCLIC SLEEP mode.

Flow control setup was updated to RCS/CTS so that waking up from sleep mode
works properly.
