Populate USB wake events for Tegra234 XUSB host controller.
These wake-up events are optional to maintain backward compatibility and
because the USB controller does not require them for normal operation.

+ The first two interrupts are required for the USB host controller. The remaining USB wake
+ event interrupts are optional. Each USB wake event is independent; it is not necessary to use
+ all of these events on a platform. The USB host controller can function even if no wake-up
+ events are defined. The USB wake event interrupts are handled by the Tegra PMC; hence, the
+ interrupt controller for these is the PMC and the interrupt IDs correspond to the PMC wake
+ event IDs. A complete list of wake event IDs is provided below, and this information is also
+ present in the Tegra TRM document.
