Subject: [PATCH] PM: Deprecate suspend/resume in device_driver

From: Ning Jiang <ning.n.jiang@...il.com>

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.
