ARM:dts:omap4-panda:Update the LED support for the panda DTS(v3)

https://patchwork.kernel.org/patch/2566421/

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.
