openrisc: re-randomize rng-seed on reboot
When the system reboots, the rng-seed that the FDT has should be re-randomized, so that the new boot gets a new seed. Since the FDT is in the ROM region at this point, we add a hook right after the ROM has been added, so that we have a pointer to that copy of the FDT.
