Subject: [PATCH 4/4] media: mt9m111: remove .s_power callback

This is in preparation of switching to the generic dev PM mechanism.
Since the .s_power callback will be removed in the near future move the
powering into the .s_stream callback. So this driver no longer depends
on the .s_power mechanism.
