The function qemu_wakeup_suspend_enabled combines the suspend

wakeup yet. Suspend is enabled here, but wakeup doesn't
actually work for microvm now.
why wakeup doesn't work?
Microvm is missing the support for wakeup now, such as, wakeup notifier,
the sleep status needs to be set, etc.
Details are in "Table 4.20: Sleep Status Register" in ACPI spec 6.5.
I've only covered the sleep support for microvm since this patch focuses
on the sleep button.
Thanks
Annie
