Jonas Ådahl 2d7a8c3ce9 kms: Don't enter power saving via updates
The way device backends implement power saving differ, and power saving
needs to contain nothing incompatible in the same update. Make it
impossible to e.g. mode set, page flip, etc while entering power save by
not using MetaKmsUpdate's at all for this.
