Subject: [driver-core PATCH v5 8/9] 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.
