dt-bindings: phy: Convert ti,da830-usb-phy to DT schema

Convert the TI DA830 USB PHY binding to DT schema format. Add "clocks"
and "clock-names" which are already in use. As they are always present,
make them required as well.

+  This device controls the PHY for both the USB 1.1 OHCI and USB 2.0 OTG
+  controllers on DA8xx SoCs.
+
+  It also requires a "syscon" node with compatible = "ti,da830-cfgchip", "syscon"
+  to access the CFGCHIP2 register.
