arm64: tegra: Disable XUSB support on Jetson TX2

Browse Source 
The recently introduced XUSB support for Jetson TX2 is causing boot, CPU
hotplug and suspend/resume failures according to several reports.

Temporarily work around this by disabling the XUSB controller and XUSB
pad controller nodes in device tree, while we figure out what's causing
this.
