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.

Thanks for fixing this - this is a key fix else, GPIO_7 which controls
VSEL for VDD_MPU on PandaBoard-ES will create all kind of ruckus (change
voltage on heartbeat)!

Good point why would I call it mmc and then set the trigger to gpio.

Will fix it.
