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 Change-Id: I99237323639df1cb72e3a81bcfed869900a2eefa Signed-off-by: Karthikeyan Ramasubramanian <kramasub@google.com> Reviewed-on: https://review.coreboot.org/c/31258 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
