[PATCH 3/4] usb: serial: spcp8x5: don't keep usb_device_id

[Gary Guo]

USB probe functions should not keep usb_device_id for longer than probe due
to presence of dynamic ID removal. USB serial does not support ID removal,
however in this case only driver_data is ever needed, there is no reason
keeping the usb_device_id in the first place, so convert it as well.
