[PATCH v3 3/6] spi: spidev: add compatible for arduino spi mcu interface

[Riccardo Mereu <r.mereu.kernel@arduino.cc>]

From: Riccardo Mereu <r.mereu@arduino.cc>

Add compatible entry in spidev describing in Arduino UnoQ single-board
computer the interface between Qualcomm QRB2210 microprocessor and
STMicroelectronics STM32U585 microcontroller.
It is handled in user space by the arduino-router service.
