Subject: [driver-core PATCH v10 7/9] PM core: Use new async_schedule_dev
command
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.
