openrisc: restart: Call common handlers before hanging 



Currently openrisc will print a message and then hang in an infinite
loop when rebooting.

This patch adopts some code from ARM, which calls the common restart
infrastructure and hangs after a small delay if the restart infra
doesn't do anything.
