Certain QMI modems will start communicating in rawip mode after
bootup, and will not work properly if communication starts off in
ethernet mode. So add a module parameter, rawip_as_default, that
can be used to load the qmi driver in rawip mode.
The advantage compared to changing rawip at a later point using
sysfs is that the os will not detect the device and start talking
to it while the driver is still in incorrect mode.
