App "example_power_gating_core" cannot be built

[JuanSapriza]

During the test for PR #239 it was seen that a parameter number issue was introduced into the example_power_gating_core app, preventing it from being built. The problem was existing before, but was hiding in a #ifdef that evaluated as false, so the code was not compiled.
This blocks the deployment of the CI of #239
Below the output of the compiler. This was built with GCC on the X-HEEP builder docker container.

This needs to be fixed by @Ho3eintaji in #246

[Ho3eintaji]

it is still previous version, however, pass pin input w/o shift and state is not used so just pass sth, then should be fine.
