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.

Hello Dan,
The OUTPUT | MODE 3 in the comments were added so people shouldn't
have to look at the TRM to find what each constant number meant. But
now using the macros this is not needed anymore, so I don't think is
necessary to keep that on the comments.
Best regards,
Javier
