ok ... but that is really strange, because looking at gpio-keys.c I see
it checking the individual button wakeup-property before setting
the irq-wake in gpio_keys_enable_wakeup() .

Ah, but I guess manually disabling/enabling wakeup via sysfs only
works for the whole device and all wakeup buttons.

In general this sounds more like a gpio-keys deficit, but in the end
we can keep the separate gpio-key nodes here, they don't violate any
dt-bindings ;-) .
