Current controller adaptation

Current controller adaptation can be used to adapt the P gain of the current controller and
the dynamic precontrol of the Iq current controller depending on the current. The current
controller adaptation is directly activated with setting p1402.2 = 1 or deactivated with
p1402.2 = 0. It is automatically activated with p1959.5 (p1959.5 = 1) or deactivated (p1959.5
= 0).

When swapping the iq interpolation points (e.g. for ASM), the current controller adaptation
appears as follows:
