The suspend/resume will not be called if they are defined in device_driver directly, PM core will only use suspend/resume function in dev_pm_ops. Thus we shall mark the old suspend/resume deprecated and make them scheduled for removal.

Make suspend/resume callbacks in device_driver deprecated and scheduled for removal since they are not used in PM core anymore.
Legacy drivers who still use them need to move suspend/resume callbacks to dev_pm_ops.
