Even when CONFIG_PM=n, we try to scale the boot voltage to a sane, known value using OPP table to find matching voltage based on boot frequency. This should be done, even when CONFIG_PM=n to avoid mis-configured bootloaders and/or boot voltage assumptions made by boot loaders. Also fixes various compile problems due to depenencies between voltage domain and powerdomain code (also present when CONFIG_PM=n).
