[PATCH 07/10] ux500: added snowball-digio.c

[mathieu.poirier at linaro.org]

From: Alessandro Rubini <rubini at gnudd.com>

This file includes definitions for the output led and 5 input buttons,
4 on the strip on the side and one soldered near the mmc slot.

This work is originally by Gregory Hermant, split by me to a
separate file.
