dt-bindings: usb: atmel,at91rm9200-udc: convert to DT schema 



Convert Atmel AT91 USB Device Controller (UDC) binding to DT schema.
Changes during conversion:
- Include "atmel,pullup-gpio" and "atmel,matrix" in the properties since
  they are required by existing in-tree DTS definitions.

description:

  The Atmel AT91 USB Device Controller provides USB gadget (device-mode)

  functionality on AT91 SoCs. It requires a peripheral clock and an AHB

  clock for operation and may optionally control VBUS power through a GPIO.

Atmel SOC USB controllers



AT91 USB device controller



Required properties:

 - compatible: Should be one of the following

	       "atmel,at91rm9200-udc"

	       "atmel,at91sam9260-udc"

	       "atmel,at91sam9261-udc"

	       "atmel,at91sam9263-udc"

 - reg: Address and length of the register set for the device

 - interrupts: Should contain macb interrupt

 - clocks: Should reference the peripheral and the AHB clocks

 - clock-names: Should contain two strings

		"pclk" for the peripheral clock

		"hclk" for the AHB clock



Optional properties:

 - atmel,vbus-gpio: If present, specifies a gpio that needs to be

   activated for the bus to be powered.
