[media] soc-camera: mt9m111: Fix auto-exposure control 

Commit f9bd584365 changed V4L2_CID_EXPOSURE_AUTO
from boolean to enum, and commit af8425c54b
changed the creation of this control into a menu for the mt9m111. However,
mt9m111_set_autoexposure() is still interpreting the value set for this control
as a boolean, which also conflicts with the default value of this control set to
V4L2_EXPOSURE_AUTO (0).
This patch makes mt9m111_set_autoexposure() interpret the value set for
V4L2_CID_EXPOSURE_AUTO as defined by enum v4l2_exposure_auto_type.
