[PATCHv2 1/6] omap3: Add external VBUS power switch and overcurrent detect on IGEP v2 board.

[Enric Balletbo i Serra <eballetbo@gmail.com>]

GPIO for various devices are missing from the board initialization.
This patch adds support for the VBUS and over current gpios.  Without this
patch, input/outputs from these two sources are ignored.
