net: fsl-mc: sync DPIO MC APIs

Sync the Data Path IO 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.
