* In ./src/core_atmosphere:

  -> removed package bl_mynn_in from packages included for nc and tend_nc. the
     array declaration for nc, nifa, nwfa, tend_nc, tend_nifa, and tend_nwfa
     now includes the same packages.

  -> in ./physics/mpas_atmphys_interface.F, added arrays nifa_p, and nwfa_p for
     the PBL option "bl_mynn".

  -> in ./physics/mpas_atmphys_todynamics.F, only updates tend_scalars(index_nc,
     tend_scalars(index_nifa, and tend_scalars(index_nwfa due to PBL processes
     when the microp_scheme option is "mp_thompson_aerosols".

  These changes are needed to run the MYNN PBL scheme without the aerosol-aware
  option of the Thompson cloud microphysics scheme.
