wakeup-source is valid for any device with an interrupts property
already, so I don't think this is necessary.
Do you mean it is not necessary on SPI level or not necessary at all? Or
you disagree with wording? Because we do need a way to say that on given
platform the device is supposed to be configured as a wakeup source.
