phy: tegra: Add support for Tegra238 XUSB pad controller

Add support for the Tegra238 XUSB pad controller by populating the
Tegra238 specific SoC data for the controller. The Tegra238 has three
USB2 and USB3 ports, uses the same port ops as Tegra186 and has the
same supplies as Tegra194. Due to the dependencies the Tegra238 device
has on the Tegra186 port ops and Tegra194 supplies, drop the compile
time guards around these structures.
