Unless I'm doing something wrong, I didn't get any warning with "make dtbs
W=1". In fact many H3 boards have a node with this name and not a single
warning is produced with this command for underscores (there are other
warnings though).
Actually, several H3 DT files have nodes like "sound_spdif" or "wifi_pwrseq". It
seems like warnings are triggered only for children of soc node.

Binding doesn't say anything about what happens if label is missing. Driver
sets generic description "gpio_keys" in such case, which is not something that
we want.
