[PATCH 2/4] driver core: auxiliary bus: Add driver data helpers

["David E. Box" <david.e.box@linux.intel.com>]

Adds get/set driver data helpers for auxiliary devices.

Note, I have another patchset that modifies current auxiliary drivers to
use this new helper. But since it touches 5 different subsystems, I plan to
submit it after this series is accepted.
