omap3: beaglexm: fix power on of DVI

TFP410 DVI chip is used to provide display out.
This chip is controlled by 2 lines:
LDO which supplies the power is controlled over gpio + 2
and the enable of the chip itself is done over gpio + 1
NOTE: the LDO is necessary for LED, serial blocks as well.

gpio + 1 was used to sense USB overcurrent in vanilla beagle.

Without this fix, the display would not function as the LDO
remains shut down.
