From: Thierry Reding <treding@nvidia.com>

Convert the old plain-text device tree bindings for the USB EHCI
controller found on NVIDIA Tegra SoCs to the json-schema format.

Signed-off-by: Thierry Reding <treding@nvidia.com>
---
Changes in v2:
- drop unneeded clock-names property
- fix indentation issues
