media: soc-camera: should pass the i2c_client->dev to .reset() function

As .power() and .reset() function defined as a pair similar functions.
But the .reset() use the soc-camera device's dev as parameter.
And .power() use the i2c-client's dev.

This patch will pass the i2c-client's dev to .reset() function, same as
.power().
