Subject: [PATCH v11 3/3] [media] imx214: Fix range for V4L2_CID_EXPOSURE

Going above 3184 changes the frame-rate of the sensor. Without this
patch there is no way to change the exposure without affecting the
frame-rate.

With the proper documentation we should be able the change the
frame-rate at wish, but until that happens we just cap what the sensor
can do.
