dt-bindings: Changes for v5.7-rc1

New IDs are added for clocks that are controlled by the PMC. This
replaces older IDs that were erroneously provided by the clock and reset
controller.

This also adds device tree bindings for XUSB pad controller support on
Tegra194 as well as USB role switching on NVIDIA Tegra SoCs.
