I dug through our old code reviews and found this message relating to testing
reboot over several thousand times in our testbed:
After the slow clock has been enabled on the reset controller via upstream
changes, the dram disable access and power down code is causing the SAM9G25
to hang occasionally on reboot. Using the simple reset function provided
for SAMA5D3 instead.
So it appears to be a workaround for a bug that existed ~2 years ago,
