[PATCH v2] power: reset: keystone: Use register_sys_off_handler(SYS_OFF_MODE_RESTART)

[Andrew Davis]

Function register_restart_handler() is deprecated. Using this new API
removes our need to keep and manage a struct notifier_block.

Signed-off-by: Andrew Davis <afd@xxxxxx>

Changes for v2:
 - Use devm_ version of register_sys_off_handler() to keep return type int
