staging: gdm724x: constantify the struct device_type usage

Since commit aed65af1cc2f ("drivers: make device_type const"), the
driver core can properly handle constant struct device_type. Move the
wwan_type variable to be a constant structure as well, placing it into
read-only memory which can not be modified at runtime.
