[PATCH v4 5/6] dt-bindings: phy: samsung,usb3-drd-phy: add ExynosAutov920 combo SS phy

[Pritam Manohar Sutar]

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 a dedicated compatible string for USB combo SS phy found in this
SoC. The SoC requires two clocks, named "phy" and "ref" and various
power supplies (regulators) for the internal circuitry to work.
The required voltages are:
* avdd075_usb - 0.75v
* avdd18_usb20 - 1.8v
* avdd33_usb20 - 3.3v

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