driver model: clean up struct bus_type a bit.

- Remove devices list, in favor of using the list in the subordinate
  devices subsystem.
- Rename devsubsys to 'devices' and drvsubsys to 'drivers'.
- Use bus's rwsem when iterating over drivers, instead of the 
  subordinate driver subsystem's. (We use that one when adding the 
  driver, and binding it to devices).
