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

CS pin added on pinctrl0 property is causing spidev to return -ENODEV
since that GPIO is already part of spi5 pinmuxing.

Fixes: 3f745bc0f11f ("arm64: dts: qcom: qrb2210: add dts for Arduino unoq")

Changes since V2:
	- Changed spidev@0 nodename to mcu@0.
	- Changed properties order in same node to match DTS coding
	  style.
