Subject: [PATCH v3 12/19] power: reset: msm-poweroff: Use devm_register_sys_off_handler(POWER_OFF)
Use this helper to register sys_off handler. Drivers should move away from
setting pm_power_off directly as it only allows for one handler. The new
way allows for trying multiple if the first one doesn't work.
