dt-bindings: trivial-devices: add arduino spi mcu interface

Add unoq mcu interface. It describes an iterface between Qualcomm
QRB2210 microprocessor and STMicroelectronics STM32U585 microcontroller
on Arduino UnoQ single-board computer.
This is a trivial device since it's usage is handled in user space
by the arduino-router service.
