The GPIO for LED D1 on the omap4-panda a1-a3 rev and the omap4-panda-es
are different.

A1-A3 = gpio_wk7
ES = gpio_110

There is no change to LED D2

Abstract away the pinmux and the LED definitions for the two boards into
the respective DTS files.

That patch was good... until Florian introduces some new constant to
improve the readability of the DTS [1].

Could you rebase on the lastest for_3.11/dts and use the macros for the
GPIO and pinctrl nodes?

Thanks,
Benoit
