arm: dts: imx943-evk: Add label for gpio expander devices

Because the i2c address of some gpio expander devices are same, so
in dts they have same node name which lead to same gpio device name.
Users can't get the GPIO through GPIO API or GPIO command.
Add the label to each gpio expander node, hence give unique name.
