dt-bindings: usb: Convert DWC2 bindings to json-schema

Convert DWC2 bindings to DT schema format using json-schema.
DWC2 is widely use but a couple of compatibles and properties
(vusb_d-supply,vusb_a-supply) were missing in dwc2.txt, the
patch add them.

-Platform DesignWare HS OTG USB 2.0 controller
------------------------------------------------------
-
-Required properties:
-- compatible : One of:
-  - brcm,bcm2835-usb: The DWC2 USB controller instance in the BCM2835 SoC.
-  - hisilicon,hi6220-usb: The DWC2 USB controller instance in the hi6220 SoC.
-  - rockchip,rk3066-usb: The DWC2 USB controller instance in the rk3066 Soc;
-  - "rockchip,px30-usb", "rockchip,rk3066-usb", "snps,dwc2": for px30 Soc;
-  - "rockchip,rk3188-usb", "rockchip,rk3066-usb", "snps,dwc2": for rk3188 Soc;
-  - "rockchip,rk3288-usb", "rockchip,rk3066-usb", "snps,dwc2": for rk3288 Soc;
-  - "lantiq,arx100-usb": The DWC2 USB controller instance in Lantiq ARX SoCs;
-  - "lantiq,xrx200-usb": The DWC2 USB controller instance in Lantiq XRX SoCs;
-  - "amlogic,meson8-usb": The DWC2 USB controller instance in Amlogic Meson8 SoCs;
-  - "amlogic,meson8b-usb": The DWC2 USB controller instance in Amlogic Meson8b SoCs;
-  - "amlogic,meson-gxbb-usb": The DWC2 USB controller instance in Amlogic S905 SoCs;
-  - "amlogic,meson-g12a-usb": The DWC2 USB controller instance in Amlogic G12A SoCs;
-  - "amcc,dwc-otg": The DWC2 USB controller instance in AMCC Canyonlands 460EX SoCs;
-  - snps,dwc2: A generic DWC2 USB controller with default parameters.
-  - "st,stm32f4x9-fsotg": The DWC2 USB FS/HS controller instance in STM32F4x9 SoCs
-  configured in FS mode;
-  - "st,stm32f4x9-hsotg": The DWC2 USB HS controller instance in STM32F4x9 SoCs
-  configured in HS mode;
-  - "st,stm32f7-hsotg": The DWC2 USB HS controller instance in STM32F7 SoCs
-    configured in HS mode;
-- reg : Should contain 1 register range (address and length)
-- interrupts : Should contain 1 interrupt
-- clocks: clock provider specifier
-- clock-names: shall be "otg"
-Refer to clk/clock-bindings.txt for generic clock consumer properties
-
-Optional properties:
-- phys: phy provider specifier
-- phy-names: shall be "usb2-phy"
-- vbus-supply: reference to the VBUS regulator. Depending on the current mode
-  this is enabled (in "host" mode") or disabled (in "peripheral" mode). The
-  regulator is updated if the controller is configured in "otg" mode and the
-  status changes between "host" and "peripheral".
-Refer to phy/phy-bindings.txt for generic phy consumer properties
-- dr_mode: shall be one of "host", "peripheral" and "otg"
-  Refer to usb/generic.txt
-- g-rx-fifo-size: size of rx fifo size in gadget mode.
-- g-np-tx-fifo-size: size of non-periodic tx fifo size in gadget mode.
-- g-tx-fifo-size: size of periodic tx fifo per endpoint (except ep0) in gadget mode.
-- snps,need-phy-for-wake: If present indicates that the phy needs to be left
-                          on for remote wakeup during suspend.
-- snps,reset-phy-on-wake: If present indicates that we need to reset the PHY when
-                          we detect a wakeup.  This is due to a hardware errata.
-
-Deprecated properties:
-- g-use-dma: gadget DMA mode is automatically detected
-
-Example:
-
-        usb@101c0000 {
-                compatible = "ralink,rt3050-usb, snps,dwc2";
-                reg = <0x101c0000 40000>;
-                interrupts = <18>;
-		clocks = <&usb_otg_ahb_clk>;
-		clock-names = "otg";
-		phys = <&usbphy>;
-		phy-names = "usb2-phy";
-		snps,need-phy-for-wake;
-        };
