powerpc/board/t4240rdb: Enable VID support
The fuse status register provides the values from on-chip
voltage ID efuses programmed at the factory. These values
define the voltage requirements for the chip. u-boot reads
FUSESR and translates the values into the appropriate
commands to set the voltage output value of an external
voltage regulator.
