dt-bindings: phy: samsung,usb3-drd-phy: add gs101 compatible

Add a dedicated google,gs101-usb31drd-phy compatible for Google Tensor
gs101 SoC.

It needs additional clocks enabled for register access, and additional
memory regions (PCS & PMA) are required for successful configuration.

It also requires various power supplies (regulators) for the internal
circuitry to work. The required voltages are:
* pll-supply: 0.85V
* dvdd-usb20-supply: 0.85V (+10%, -7%)
* vddh-usb20-supply: 1.8V (+10%, -7%)
* vdd33-usb20-supply: 3.3V (+10%, -7%)
* vdda-usbdp-supply: 0.85V
* vddh-usbdp-supply: 1.8V
