media: i2c: ov02a10: Replace client->dev usage

Browse Source 
The driver needs to access the struct device in many places, and
retrieves it from the i2c_client itself retrieved with
v4l2_get_subdevdata(). Store it as a pointer in struct ov02a10 and
access it from there instead, to simplify the driver.
