I2c mux tca9548 for imx462

hello matanh,

there should be sensor operations called by probing process.
you may check reference drivers as an example,

static struct camera_common_sensor_ops imx185_common_ops = {
        .numfrmfmts = ARRAY_SIZE(imx185_frmfmt),
        .frmfmt_table = imx185_frmfmt,
        .power_on = imx185_power_on,
        .power_off = imx185_power_off,
        .write_reg = imx185_write_reg,
        .read_reg = imx185_read_reg,
        .parse_dt = imx185_parse_dt,
        .power_get = imx185_power_get,
        .power_put = imx185_power_put,
        .set_mode = imx185_set_mode,
        .start_streaming = imx185_start_streaming,
        .stop_streaming = imx185_stop_streaming,
};
