SteadyState for Modelica.Blocks.Continuous.PI

[HansOlsson]

If you look in Modelica.Blocks.Continuous.PI you see that y_start is enabled for steady-state (Modelica.Blocks.Types.Init.SteadyState), but not used in that case!

If you want to set a guess-value it makes more sense to set x_start in that case - or in rare cases y.start.

I thus believe that the simplest solution would be to just modify the enable-attribute.
