At the moment we set the algorithm type for 4g5g to the same algorithm
type we use for 3g. There is no way to select the algorithm type for
4g5g individually.
With the Advent of TUAK users might need to set the 4g5g algorithm to
TUAK and the Algorithm used for 3g to something else (e.g. Milenage). So
let's allow to select the algorithm for 4g5g individually, but only if
the user explicitly defines it.
