usb: dwc3: exynos: add support for Google Tensor gs101
The Exynos-based Google Tensor gs101 SoC has a DWC3 compatible USB
controller and can reuse the existing Exynos glue. Add the
google,gs101-dwusb3 compatible and associated driver data. Four clocks
are required for USB for this SoC:
* bus clock
* suspend clock
* Link interface AXI clock
* Link interface APB clock
