[AS9716-32D] Support i2c mux reset (#10492) 
Why I did it
    Prevent from i2c bus to get locked.

How I did it
    Add sysfs driver to access ioport.
    Command to reset i2c mux:
    echo 1 > /sys/devices/platform/as9716_32d_ioport/i2c_mux_rst
    Command to bring i2c mux out of reset:
    echo 0 > /sys/devices/platform/as9716_32d_ioport/i2c_mux_rst

[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.
