Parts that poke port specific HW blocks like the encoder HW state readout or connector hotplug detect code need a way to check whether required power domains are on or enable/disable these. For this purpose add a set of power domains that refer to the port HW blocks. Get the proper port power domains during modeset. For now when requesting the power domain for a DDI port get it for a 4 lane configuration. This can be optimized later to request only the 2 lane power domain, when proper support is added on the VLV PHY side for this. Atm, the PHY setup code assumes a 4 lane config in all cases.
