net: fsl-mc: sync DPSPARSER MC APIs
Sync the Data Path Soft Parser APIs to their latest form, this
means the layout of each command is created based on structures which
clearly describe the endianness of each field rather than some macros.
The command version is kept in place, meaning that the minimum MC
version accepted is not changed in any way.
