This is already possible. You set the SCI mask such that non-critical
SCI's are masked. I don't think we have a generic way yet for userspace
to tell the kernel what mask bits to set though.
The big issue however, was that until q2d08a host -> EC communications
was um, a bit unreliable. So turning of all the wakeups and then never
being able to turn them back on was a concern. Now I think I have that
under control and we can move toward this type of control.
