gma power: Allow to explicitly enable DDI/Aux power
We used to enable power for DP-aux channels quite implicitly by faking configs that use a specific port. As Tiger Lake requires us to enable a DDI ports power late during the modesetting sequence, we introduce a new API for such cases, and also use it for the DP-aux case.
TODO: Needs testing on HSW+/SKL+/BXT systems because I'm unsure if the PDW needs to be enabled as well.
