realtek: fix node addresses for RTL839x

The address in some node names doesn't match the actual offset specified
in the DT node. Update the names to fix this.

While fixing the node names, also drop the unused node labels.

Fixes: 0a7565e53653 ("realtek: Update rtl839x.dtsi for realtek,rtl-intc, new gpio controller remove RTL8231 node")
