[PATCH v2] ARM: dts: fix gpio-keys wakeup-source property

[Sudeep Holla]

The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
two boolean properties to enable gpio buttons as wakeup source:
1. "wakeup-source" or
2. the legacy "gpio-key,wakeup"

However juno, ste-snowball and emev2-kzm9d dts file have a undetected
"wakeup" property to indictate the wakeup source.

This patch fixes it by making use of "wakeup-source" property.

Hi ARM-SoC group,

Please consider this as a fix for v4.3 if possible.

v2->v1[1] :
 - included all the reviewed/ack tags, also posting this fix independently

Regards,
Sudeep
