ARM: tegra: ventana: disable usb1 vbus gpio
disable the usb1 vbus gpio in kernel and not depend on bootloader
to disable the vbus initially.
Currently, the kernel enables and disables the vbus when
the otg is configured to host mode, but when the system boots
with no cable connected the kernel relies on the bootloader
to turn the vbus off.
This CL removes that dependency.
