arm64: tegra: Device tree fixes for v5.2-rc1

This contains one patch to disable the recently added XUSB support on
Jetson TX2 which is reported to cause boot and CPU hotplug failures in
some cases and doesn't allow the core power rail to be switched off.

Furthermore there are some changes to enable IOMMU support on more
devices. This is needed in order to prevent these devices from breaking
with the policy change in the ARM SMMU driver to break insecure devices
that is currently headed for v5.2.
