[PATCH v2] OMAP3EVM: ehci: Fix EHCI support

[Gupta, Ajay Kumar]

Hi,
> Set the VAUX2 regulator supply to 1.8V for the HSUSB host interface.
> Gpio 2 of the TPS65950 has to be set to zero in order to enable the

TPS65950 GPIO2 is not to enable HSUSB2 clock but to enable chip u131
On omap3evm (rev-G) which latches USB, camera and audio lines.

Did you test EHCI port with this change ?
