[Accton] Enable pca954x i2c mux idle_disconnect for 5.10 kernel (#9745)

Enable pca954x idle_disconnect to avoid possible I2C device address conflict.

How I did it
Change pca954x device_attr idle_state to -2 (MUX_IDLE_DISCONNECT).

How to verify it
Cat pca954x device_attr idle_state and confirm the value is -2.
