Subject: [PATCH] arm64: dts: qcom: arduino-imola: fix faulty spidev node

From: Riccardo Mereu <r.mereu@...uino.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")
