[PATCH V2] arm64: dts: qcom: arduino-imola: fix faulty spidev node

[Riccardo Mereu]

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")

note: usually one would include a short changelog under the --- line,
but here I still remember it was "also remove pinctrl-names override"

Of you're modifying this node, you should fix the nodename too. "spidev"
isn't a type of device. It should probably either be "mcu@" or whatever
the mcu is used for.
