PPC: E500: Implement reboot controller
When Linux reboots an e500 VM, it writes to a magic register in the "global-utilities" device indicated by the device tree. We were not emulating that device so far, rendering the VM reboot-less. This patch implements that device with only the reboot functionality implemented and adds it to the device tree. With this patch applied, I can successfully reboot a -M mpc8544ds VM.
