phy: tegra: xusb: Add Tegra264 support

Browse Source 
Add support for the XUSB pad controller for Tegra264. Most of
the Tegra264 XUSB PADCTL registers definition and programming sequence
are the same as Tegra234, Tegra264 XUSB PADCTL can share the same
driver with Tegra186, Tegra194, and Tegra234 XUSB PADCTL.
