ARM: tegra: Workaround UDC boot issues only if necessary

Browse Source 
Resetting the USB device controller on boot is only necessary if the SoC
actually has a UDC controller and U-Boot enables support for it. All the
Tegra boards support UDC via the ChipIdea UDC driver, so make the UDC on
boot workaround depend on the ChipIdea UDC driver.

This prevents a crash on Tegra186 which does not have the ChipIdea UDC.
