The driver sets wakeup enable by default. But not all uarts are meant to
be wakeup enabled. Change the default to be wakeup capable but not
enabled. The user can enable wakeup when needed.

In addition to the user enabling via sysfs, this driver should also look
for the `wakeup-source` DT property, and enable when that property is set.
