Default omap3: Add GPIO's for external VBUS power switch and overcurrent detect on IGEP v2 board.

SRU Justification:

Impact: 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.
