Convert fsl-usb binding doc to yaml format.

Additional change:
- Remove port0 and port1 from required list.
- Use common usb-drd.yaml for dr_mode property
- Keep two difference examples.
- Add interrupts to required property list.
- Remove #address-cells and #size-cells in example.
- Use predefined irq type macro.

It cannot be standalone and not-standalone. Cannot be both. Choose one.

Keep the same order as in "properties:". Preferably this order, so
adjust "properties:" to match "required:".

dt_binding_check report error without '|'
fsl,usb2.yaml:15:11: [error] syntax error: mapping values are not allowed here (syntax)

"Practice:" impact yaml parse.

-Freescale SOC USB controllers
-
-The device node for a USB controller that is part of a Freescale
-SOC is as described in the document "Open Firmware Recommended
-Practice : Universal Serial Bus" with the following modifications
-and additions :
-
-Required properties :
- - compatible : Should be "fsl-usb2-mph" for multi port host USB
-   controllers, or "fsl-usb2-dr" for dual role USB controllers
-   or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121.
-   Wherever applicable, the IP version of the USB controller should
-   also be mentioned (for eg. fsl-usb2-dr-v2.2 for bsc9132).
- - phy_type : For multi port host USB controllers, should be one of
-   "ulpi", or "serial". For dual role USB controllers, should be
-   one of "ulpi", "utmi", "utmi_wide", or "serial".
- - reg : Offset and length of the register set for the device
- - port0 : boolean; if defined, indicates port0 is connected for
-   fsl-usb2-mph compatible controllers.  Either this property or
-   "port1" (or both) must be defined for "fsl-usb2-mph" compatible
-   controllers.
- - port1 : boolean; if defined, indicates port1 is connected for
-   fsl-usb2-mph compatible controllers.  Either this property or
-   "port0" (or both) must be defined for "fsl-usb2-mph" compatible
-   controllers.
- - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
-   controllers.  Can be "host", "peripheral", or "otg".  Default to
-   "host" if not defined for backward compatibility.
-
-Recommended properties :
- - interrupts : <a b> where a is the interrupt number and b is a
-   field that represents an encoding of the sense and level
-   information for the interrupt.  This should be encoded based on
-   the information in section 2) depending on the type of interrupt
-   controller you have.
-
-Optional properties :
- - fsl,invert-drvvbus : boolean; for MPC5121 USB0 only. Indicates the
-   port power polarity of internal PHY signal DRVVBUS is inverted.
- - fsl,invert-pwr-fault : boolean; for MPC5121 USB0 only. Indicates
-   the PWR_FAULT signal polarity is inverted.
-
-Example multi port host USB controller device node :
-	usb@22000 {
-		compatible = "fsl-usb2-mph";
-		reg = <22000 1000>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		interrupt-parent = <700>;
-		interrupts = <27 1>;
-		phy_type = "ulpi";
-		port0;
-		port1;
-	};
-
-Example dual role USB controller device node :
-	usb@23000 {
-		compatible = "fsl-usb2-dr";
-		reg = <23000 1000>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		interrupt-parent = <700>;
-		interrupts = <26 1>;
-		dr_mode = "otg";
-		phy = "ulpi";
-	};
-
-Example dual role USB controller device node for MPC5121ADS:
-
-	usb@4000 {
-		compatible = "fsl,mpc5121-usb2-dr";
-		reg = <0x4000 0x1000>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		interrupt-parent = < &ipic >;
-		interrupts = <44 0x8>;
-		dr_mode = "otg";
-		phy_type = "utmi_wide";
-		fsl,invert-drvvbus;
-		fsl,invert-pwr-fault;
