Add function to allow the configuation fo the VDCDC2 register by external users, to allow changing of the standard and low-power running modes. This is needed, for example, for the Simtec IM2440D20 where we need to use the low-power mode to shutdown the LDO/DCDC that are not needed during suspend (saving substantial power) and the runtime use of the low-power mode to change VCore.
