usb: xhci: tegra: Support USB wakeup function for Tegra234

Browse source

When the system is suspended, USB hot-plugging/unplugging can trigger
wake events of the Tegra USB host controller.
Enable support for USB wake-up events by parsing device-tree to see if
the interrupts for the wake-up events are present and if so configure
those interrupts. Note that if wake-up events are not present, still
allow the USB host controller to probe as normal.
