dt-bindings: usb: Convert fsl-usb to yaml

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.
