Just an update for the people that have same problem:
In the CHARMM FF the out-of-plane motion is handled by the IMPH keyword in
the param file (see http://www.charmm.org/documentation/c32b2/parmfile.html
However, to my understanding CP2K doesn't recognize those, but instead
using OPBEND keyword under FORCEFIELD looks like to be working for me, just
note that you need to use MM2 type with correct unit.
