ARM / Integrator: Use struct syscore_ops for core PM
Replace the sysdev class and struct sys_device used for power management by the Integrator interrupt-handling code with a struct syscore_ops object which is simpler. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
