[PATCH v1 2/8] MT9M114: Add pad-slew-rate DT-binding

The MT9M114 supports the different slew rates (0 to 7) on the output pads.
At the moment, this is hardcoded to 7 (the fastest rate).
The user might want to change this values due to EMC requirements.

Add the 'pad-slew-rate' property to the MT9M114 DT-bindings for selecting
the desired slew rate.
