This patch enables Vbus required for USB 2.0 controller.

Signed-off-by: Vivek Gautam gautam.vivek@samsung.com Signed-off-by: Rajeshwari Shinde rajeshwari.s@samsung.com ---

Changes from v3: - Rebased on top of u-boot-samsung/master.

Changes from v2: - Rebased on top of u-boot-usb/next - Enclosed the function definition for board_usb_vbus_init() inside "CONFIG_USB_EHCI_EXYNOS"

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.
