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

Browse Source 
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.

TI DA8xx/OMAP-L1xx/AM18xx USB PHY
Required properties:
- compatible: must be "ti,da830-usb-phy".
- #phy-cells: must be 1.
This device controls the PHY for both the USB 1.1 OHCI and USB 2.0 OTG
controllers on DA8xx SoCs. Consumers of this device should use index 0 for
the USB 2.0 phy device and index 1 for the USB 1.1 phy device.
It also requires a "syscon" node with compatible = "ti,da830-cfgchip", "syscon"
to access the CFGCHIP2 register.
Example:
cfgchip: cfgchip@1417c {
compatible = "ti,da830-cfgchip", "syscon";
reg = <0x1417c 0x14>;
};
usb_phy: usb-phy {
compatible = "ti,da830-usb-phy";
#phy-cells = <1>;
};
usb20: usb@200000 {
compatible = "ti,da830-musb";
reg = <0x200000 0x1000>;
interrupts = <58>;
phys = <&usb_phy 0>;
phy-names = "usb-phy";
};
usb11: usb@225000 {
compatible = "ti,da830-ohci";
reg = <0x225000 0x1000>;
interrupts = <59>;
phys = <&usb_phy 1>;
phy-names = "usb-phy";
};
