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 port's power late during the modesetting sequence,  we introduce
a new API for such cases, and also use it for the DP-aux case.

Tested on HSW, and BXT & CFL where we enable PW2 explicitly now.
