arm64: dts: exynos: gs101: add USB & USB-phy nodes

Add the USB 3.1 Dual Role Device (DRD) controller and USB-PHY nodes for
Google Tensor GS101.

The USB 3.1 DRD controller has the following features:
* compliant with both USB device 3.1 and USB device 2.0 standards
* compliant with USB host 3.1 and USB host 2.0 standards
* supports USB device 3.1 and USB device 2.0 interfaces
* supports USB host 3.1 and USB host 2.0 interfaces
* full-speed (12 Mbps) and high-speed (480 Mbps) modes with USB device
  2.0 interface
* super-speed (5 Gbps) mode with USB device 3.1 Gen1 interface
* super-speed plus (10 Gbps) mode with USB device 3.1 Gen2 interface
* single USB port which can be used for USB 3.1 or USB 2.0
* on-chip USB PHY transceiver
* DWC3 compatible
* supports up to 16 bi-directional endpoints
* compliant with xHCI 1.1 specification
