dt-bindings: phy: samsung,usb3-drd-phy: add ExynosAutov920 HS phy compatible 



Document support for the USB20 phy found on the ExynosAutov920 SoC. The
USB20 phy is functionally identical to that on the Exynos850 SoC, so no
driver changes are needed to support this phy. However, add a dedicated
compatible string for USB20 phy found in this SoC.

This phy needs 0.75v, 0.18v and 3.3v supplies for its internal
functionally. Power Supply's names are as per phy's User Data-Book.
These names, (dvdd, vdd18 and vdd33), are considered  for 0.75v, 1.8v
and 3.3v respectively.
