dt-bindings: usb: Add wake-up support for Tegra234 XUSB host controller
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
48
+
remaining USB wake event interrupts are optional. Each USB wake event is
49
+
independent; it is not necessary to use all of these events on a
50
+
platform. The USB host controller can function even if no wake-up events
51
+
are defined. The USB wake event interrupts are handled by the Tegra PMC;
52
+
hence, the interrupt controller for these is the PMC and the interrupt
53
+
IDs correspond to the PMC wake event IDs. A complete list of wake event
54
+
IDs is provided below, and this information is also present in the Tegra
55
+
TRM document.
