[PATCH] Add bus_type probe, remove, shutdown methods.
Add bus_type probe, remove and shutdown methods to replace the
corresponding methods in struct device_driver. This matches
the way we handle the suspend/resume methods.
Since the bus methods override the device_driver methods, warn
if a device driver is registered whose methods will not be
called.
The long-term idea is to remove the device_driver methods entirely.
