[PATCH] ARM: dts: r8a7794: replace gpio-key, wakeup with wakeup-source property

[Simon Horman]

Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

Changelog text from a similar patch by Sudeep Holla.
