rpi3/4: Add support for offlining CPUs

The hooks were populated but the power down left the CPU in limbo-land.
What we need to do - until there is a way to actually power off - is to
turn off the MMU and enter the spinning loop as if we were cold-booted.
This allows the on-call to pick up the CPU again.
