Eliminate need for global variables for the various PRM module offsets by making them part of the VP/VC common structures Eventually, these will likely be moved again, or more likely removed when VP/VC code is isolated, but for now just getting rid of them as global variabes so that the voltage domain initialization can be cleaned up.
