media: mt9t031: deprecate, move to staging

This driver is unused and depends on the deprecated soc-camera framework.
Move it to staging in preparation for being removed unless someone does
the work to convert it to a proper V4L2 subdev driver.

+This sensor driver needs to be converted to a regular
+v4l2 subdev driver. The soc_camera framework is deprecated and
+will be removed in the future. Unless someone does this work this
+sensor driver will be deleted when the soc_camera framework is
+deleted.
