mei: vsc: Don't stop/restart mei device during system suspend/resume
The dynamically created mei client device (mei csi) is used as one V4L2
sub device of the whole video pipeline, and the V4L2 connection graph is
built by software node. The mei_stop() and mei_restart() will delete the
old mei csi client device and create a new mei client device, which will
cause the software node information saved in old mei csi device lost and
the whole video pipeline will be broken.
Removing mei_stop()/mei_restart() during system suspend/resume can fix
the issue above and won't impact hardware actual power saving logic.
