Adds device nodes for two front panel LEDs.
Why do you need to change the pinmux settings? Configuring a pin as a
GPIO should override any pinmux special function selection and hence
make it irrelevant, so I don't think you should need to change the pinmux.
At first I did exactly that without changing the pinmux, but the LEDs
didn't light up. After that I compared with CompuLab source tree [1].
The pinmux was specified as in my patch. With this change the LEDs are
fully functional.
