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.

changes in version 2:
- put Minas Harutyunyan <hminas@synopsys.com> as maintainer
- remove type and description from phy property
- remove description from compatible items
- simplify samsung,s3c6400-hsotg compatible handling

Does it pass dtbs_check? Should be two strings.

Bad copy/past from the original text file.

You are right it should two strings and dt check tools don't detect 
because they see it as a different compatible.

-- 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

-  Refer to usb/generic.txt
-- g-rx-fifo-size: size of rx 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

-- snps,reset-phy-on-wake: If present indicates that we need to reset the PHY when
