For some SoCs' (like the already existing AM33xx family, or for the upcoming AM437x and DRA7 SoCs') which do not have a Voltage controller/Voltage Processor (neither the SR I2C bus to communicate with the PMIC) there is no need for a Powerdomain to have a voltage domain association since there is no auto-scaling of voltages possible using the voltage FSM. Extend the arch operations to add an api which the powerdomain core can then use to identify if a voltdm lookup and association for a powerdomain is really needed.
