SMDK5250: Enable VBus for USB 2.0 controller

This patch enables Vbus required for USB 2.0 controller.

---

Changes from v1:
- Using the old school method of setting up gpio instead of using the pinmux method, since the required gpio line here is board specific.

Dear Vivek Gautam,

Can you please rebase on top of u-boot-usb/next ?

Best regards,

Hi Marek,

CCing: Simon Glass

Since these changes were related to samsung so i based them on u-boot-samsung. :-)
I shall post a patch rebased on top of u-boot-usb/next.

Thanks & Regards
Vivek

Dear Vivek Gautam,

Oh, I'll pick this for -next.

Best regards,
