	  Enables support for the PCIe controller in the NVIDIA Tegra194 SoC to

	  work in host mode. There are two instances of PCIe controllers in

	  Tegra194. This controller can work either as EP or RC. In order to

	  enable host-specific features PCIE_TEGRA194_HOST must be selected and

	  in order to enable device-specific features PCIE_TEGRA194_EP must be

	  selected. This uses the DesignWare core.
