driver: net: fsl-mc: Prepare extended cfg for DPNI create

Management Complex FW 9.0 puts a new requirement to prepare extended
parameters which should be provided as input in dpni_create. extended
parameters includes traffic class and IP reassembly configurations.

So prepare extended parameters with default "0" as input for
dpni_create.
