description:
Switch the third argument to the _DSW method from 3 to 0. This means that
devices should be placed in the D0 state ("fully on") after resume. We were
not prepared to handle the previous value as it implied that devices could
be placed in an arbitrary power state once in S0.

Minimal functional change, given that the _DSW is seldom seen in the field.
