Driver core: clean up debugging messages

The driver core debugging messages are a mess.  This provides a unified
message that makes them actually useful.

The format for new kobject debug messages should be:
	driver/bus/class: 'OBJECT_NAME': FUNCTION_NAME: message.\n

Note, the class code is not changed in this patch due to pending patches
in my queue that this would conflict with.  A later patch will clean
them up.
