[U-Boot] [PATCH v2] odroid-XU3: Add entry for DTS EHCI GPIO

Add samsung,vbus-gpio information for the XU3. This allows the usage of
the EHCI controller on the XU3, which is connected to the SMSC LAN9514
chip (usb hub + network).

Changes since v1:
  + Correct gpio number
  + Add USB configuration in the odroid XU3 default config

Hyungwon could you add this one to your XU3 patchset if you send a next
version (assuming it looks good)?

For usb storage/network support this patch should be combined
with the exynos configuration tweaks patch i submited earlier to the list:
  Exynos: Move down common USB configuration
