[media] si2168: carry pointer to client instead of state
Carry struct i2c_client pointer inside struct dvb_frontend private pointer. This driver is I2C driver, which is represented as a struct i2c_client, so better to carry this top level structure for each routine in order to unify things. This allows further simplification.
