atmodem: Add support for IFX specific GPRS suspend notification 

The Infineon modem informs about GPRS suspend cases. For example when
GPRS is active and a call is made. If the status changes, inform the
core about this change.

This uses GPRS_SUSPENDED_UNKNOWN_CAUSE reason since the modem does not
give a clear reason why GPRS was suspended. With this reason there is
a delay before the status change gets send out as D-Bus signal.
