i915: add suspend/resume support
Add suspend/resume support to the i915 driver. Moves some of the initialization into the driver load routine, and fixes up places where we assumed no dev_private existed in some of the cleanup paths. This allows us to suspend/resume properly even if X isn't running. Signed-off-by: Dave Airlie <airlied@linux.ie>
