media: i2c: ov5647: Neither analogue gain nor exposure need EXECUTE_ON_WRITE

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

The controls for analogue gain and exposure were defined with
V4L2_CTRL_FLAG_EXECUTE_ON_WRITE. This is not required as we only need
to send changes to the sensor.
