Re: [U-Boot] [PATCH] exynos: dts: Correct USB vbus-gpio numbering for Snow

The current vbus GPIOs on snow make very little sense, their number is far above the maximum. As a result, USB doesn't work on snow.

Correct the GPIO numbering so they match the current scheme for exynos5. Tested both EHCI and XHCI to correctly work after this change.
