This code triggers the PGC powerdown sequence to disable the GPU/VPU isolation cells and gate power and then disables the PU regulator. To reenable, the reverse powerup sequence is triggered after the PU regulator is enabled again. The GPU and VPU devices in the PU power domain temporarily need to be clocked during powerup, so that the reset machinery can work.
