lib/mpi: headers cleanup
MPI headers contain definitions for huge number of non-existing functions. Most part of these functions was removed in 2012 by Dmitry Kasatkin -hifive-unleashed-5.17cf4206a99("Remove unused code from MPI library") -9e235dcaf4("Revert "crypto: GnuPG based MPI lib - additional ...") -bc95eeadf5("lib/mpi: removed unused functions") however headers wwere not updated properly. Also I deleted some unused macros.
