ARM: omap3evm: enable VBUS switch for EHCI tranceiver

Browse source

This was chosen by following the trace on the schematic from component U131
and U134 to the CPEN pin on the USB3320 device.

TWL4030.GPIO2-...->(T2_GPIO2_3V3)U131-..>nUSB2_EN-..>U134-..>EXP_nUSB2_1V8
which starts EHCI tranceiver USB3320.

This will set TWL4030.GPIO2 as output pin to drive EHCI tranceiver.
