Subject: [PATCH v9] ARM: dts: omap4-panda: Update the LED support for the panda DTS

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.

And here you could use the GPIO defines:

gpios = <&gpio4 14 GPIO_ACTIVE_HIGH>;

Same here.
