drivers/gpio_keys: Remove redundant is_wakeup_source flag
"is_wakeup_source" flag is used to indicate if the concerned device can
trigger a wakeup. This flag is redundant with the "wake" GPE event
definition. So remove the redundant flag and use the "wake" GPE event to
mark the wakeup source.
BUG=None
BRANCH=None
TEST=Boot to ChromeOS. Ensure that the device is marked as wakeup-source
in SSDT if wake GPE is configured. Ensure that the system can suspend
and the device acts as a wakeup source
