cinterion: implement SFDL update method
Most Cinterion modems allow starting firmware updates from the host via the AT^SFDL
command.
I've added a udev rule ID_MM_CINTERION_SFDL
that enables the SFDL update method. If SFDL is not available, the parent update methods are loaded.
I could not yet find the name of the update protocol itself. My suggestion so far is cinterion-sfdl
