[RFC workqueue/driver-core PATCH 4/5] driver 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 devices. 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.
