[PATCH 15/16] arm64: dts: st: enable usb on stm32mp257f-dk

STM32MP257F-DK board uses two USB controllers:
- USB 2.0 High-Speed Host, with external onboard HUB providing two
  connectors.
- USB 3.0 Super-Speed dual role Type-C port

The Type-C port management is done through integrated UCPD controller
and external TCPP03 I2C protection chip on I2C1. FUSB340 SuperSpeed
switch is used to reverse Super-Speed lines, depending on the
orientation.
