[PATCH 14/16] arm64: dts: st: enable usb on stm32mp257f-ev1

[Fabrice Gasnier]

STM32MP257F-EV1 board uses two USB controllers:
- USB Host port, with external onboard HUB providing to connectors
- USB Dual role Type-C port
Both are capable of to operate in High-Speed mode.
The Type-C port management is done through integrated UCPD controller
and external TCPP03 I2C protection chip on I2C1.
