dt-bindings: phy: qcom,qmp-usb3-dp: Add DP phy information
This binding only describes the USB phy inside the USB3 + DP "combo" phy. Add information for the DP phy and describe the sub-nodes that represent the DP and USB3 phys that exist inside the combo wrapper. Remove reg-names from required properties because it isn't required nor used by the kernel driver.
