Most of the legacy "gpio-key,wakeup" boolean property is already
replaced with "wakeup-source". However few occurrences of old property
has popped up again, probably from the remnants in downstream trees.
Replace the legacy properties with the unified "wakeup-source"
property introduced in the Linux kernel commit 700a38b27eef
("Input: gpio_keys - switch to using generic device properties")

example"
with this fragment in commit message
"Drop #address-cells and #size-cells, which are not required by the
gpio-keys binding documentation, as button sub-nodes are not devices."
