[PATCH v3 7/9] dt-bindings: phy: samsung,usb3-drd-phy: add ExynosAutov920 combo SS phy

Add a dedicated compatible string for USB combo phy found in this SoC.
The devicetree node requires two clocks, named "phy" and "ref".

This phy supports USB3.1 SSP+(10Gbps) protocol and is backwards
compatible to the USB3.0 SS(5Gbps). 'Add-on USB2.0' phy is required
to support USB2.0 HS(480Mbps), FS(12Mbps) and LS(1.5Mbps) data rates.
These two phys are combined to form a combo phy.

Add schema only for 'USB3.1 SSP+' SS phy in this commit.
