Subject: [workqueue/driver-core PATCH 5/5] PM core: Use new
 async_schedule_dev command

This change makes it so that we use the device specific version of the
async_schedule commands to defer various tasks related to power management.
By doing this we should see a slight improvement in performance as any
device that is sensitive to latency/locality in the setup will now be
initializing on the node closest to the device.
